Hello
I have a bosch ve injector pump with a manual throttle ( not fly by wire ) and I can’t get it to work.
I have it bled through properly and can get the diesel lines primed to the injectors ok but it doesn’t have enough pressure to fire the injectors at all.
I have cracked the injector pipes at the injectors and it spits diesel to all cylinders ok. I have tried a few different injectors that I know work perfect but still nothing.
Anyone have any idea as to why it hasn’t got enough pressure?
Thanks Adam
Hi Adam,
Thank you for contacting us.
This could be down to internal wear inside your fuel pump i.e the supply pump that internally creates vacuum and draws fuel up from the tank.

Hi I have a ford Mondeo Zetec 2.0 Deisel that cut out with no warning while driving on a dual carriageway and flashed up engine malfunction before everything in the cab was extinguished now it won’t restart and sounds like it has lack of fuel to fire up when key is turned to start it, have had electrics and battery checked all fine haven’t had diagnostics on yet as when recovery came there machine wouldn’t fire up any ideas what it may be. Car has driven fine with no problems up to that point so no warnings fuel had been put in night before and had driven close to 100 mile before this happened your help is much appreciated
Hi Gemma,
Thank you for contacting us.
First of all we would recommend taking it to a garage for a diagnostic.
There could be a number of things causing this problem:
Injectors
Fuel pump
Metering Valve
Blocked fuel filter
Feel free to call our workshop on 01509 633300
Hi Stu,
Many apologies for the late reply.
This could be down to neat fueling by your injectors.
Could you confirm if your vehicle has a dpf fitted?
if the DPF is blocked this can cause the injectors to overfuel to try and facilitate a regen to burn the soot content.
good morning
I have a 2006 mazda 3 1.6td, I have just replaced the EGR valve wich was faulty, it ran great for a few days but then it started stalling and being difficult to start. it will start ok if I bump start it say down a small incline or by towing. If I drive nicely it doesnt seem to do it as often, do this but if i am being a bit more aggressive it seems to cause this fault.
any advice is appreciated
Hi Steven,
Thank you for your enquiry.
This sounds like a SCV ( suction control valve) fault, which is fairly common on these engines.

Hi I have a 2007 grand voyager 2.8 crd, if had a fault code p0402 we have replaced the egr and 2 of the solenoids the engine light is not coming on now but there is still a loss of power pulling away and hills also smoking when under load. Please help
Hi Ian,
Thank you for contacting us.
P0402 does relate to EGR system.
However there are other areas of the system that could cause these symptoms to appear:
Manifold Absolute Pressure Sensor (MAP)
Differential EGR Pressure Feedback Sensor (DPFE)
EGR Valve Position Sensor (EVP)
Feel free to call our workshop on 01509 633300 Option 2, they will be more than happy to help.

Hi there, I would like to run a bigger diesel engine in my freelander. I am thinking the 2.2 Peugeot hdi engine. I would like to know if the pump management can be recoded to work on the landrover system, or the pump can be swapped for something that would work, or if you could recommend/build a pump/system that could be modified to work with the hdi engine.
Thank you for contacting us,
Unfortunately that is not something we have ever dealt with or would deal with.
If you would like to contact a company called BBA Reman on 01634 687222 they would be able to help you with this matter.
I’ve got a Mazda 6, 2.0 d, 2008. From time to time car shakes when idle, it is quite rough sometimes, sometimes it doesn’t shake all day. I took it to Mazda service, they changed 2 injectors, cleaned up body throttle, changed fuel pump valve and according to them checked everything (whatever that is) else. Car still shakes!!!! Problem is that it’s not regular and not every single time (it’s mostly fine when it’s cold, get’s worst after a longer trip, or even shorter one around the town). Last suggestion from “Mazda experts” was to change “computer” that regulates everything – at cost of £1500 around! Also before all of this i had engine oil and filter and air filters changed (not sure about quality of oil and if that can have something to do with this problem)
Please help!
Thankyou for contacting us Pawel.
Did Mazda carry out a pump relearn that is required when a new SCV on the pump is fitted?
Feel free to contact us on 01509 633300 we will be more than happy to discuss it with you.
Hi thank you for fast reply. They told me that they checked pressure in fuel pump (via their system on computer) and it shows that pressure is correct?!
Just contacted Mazda… they assuming it should have been done, but they are not sure! I’ll take the car back to them tomorrow so they can do it again! (or for the first time) any suggestions what should I ask about? what to tell them?
Thank you very much for all your help! I wish I have come to in first place!
I have a 1993 VW T4 . Diesel is leaking out of the throttle spindle on the diesel pump (only at tickover) is this a repairable part
Cheers — Steve
Hi Steve,
Thank you for contacting us.
Yes that is a repairable part. We can strip and check your pump at the same time and give you a report on its condition.
Please don’t hesitate to contact our workshop on 01509 633300.
Hi
I have a 2002 ford Focus 1.8 tdci. I’m experiencing a lack of power since the fuel filter was renewed. The garage advised the injection pump is weak and needs replacing.
The car ran perfectly before the filter change. Any suggestions?
Thanks.
Hi Andy,
Thank you for contacting us.
Do you know if the fuel filter fitted was genuine ford? also did you have this problem prior to the fuel filter being fitted.
Feel free to contact our workshop on 01509 633315 they will be happy to discuss it further with you
hi i have a seat leon tdi, 59 plate, i was driving on motorway few weeks ago, when it went into limp mode, we put it on a machine and the fault was pO234 overboost, we changed n75 valve, but it wasnt that, ive now been told it is 100% needs a new turbo? is this common? does that sound right?
many thanks
darren
Hi Darren,
Thank you for contacting us.
Unfortunately without seeing the vehicle it is hard to say whether your turbo is faulty.
There are many things that can cause symptoms of a faulty turbo.

Hi.
I have a 53 plate Vauxhall Corsa 1.3 CDTI. Had the diesel pump redone from you guys earlier on in the year and car was running fine. Since the cold weather has started it has become very difficult to start. Sometimes will start and cut straight out.
A spanner light also comes on after a few minutes of driving. Had it checked at a garage and it has a low glow voltage error code. Had new glow plugs and glow control module fitted and code cleared. Has not fixed the problem. With the big freeze coming I fear it not starting at all.
Vauxhall seem to be scratching their heads and think it’s the ecu. Any help would be much appreciated.
Hi Gurdip,
Thank you for contacting us.
Could you provide us with the registration so we can see what work was carried out on the vehicle.
It could be many things that are causing your problem such as fuel leak back, air ingress.
We would be more than happy to look at the vehicle for you and see if we can help find a cause of your problem
Please don’t hesitate to call the workshop on 01509 633315
Hi Nathan
I have a 2004 ford ranger/mazda B series with a 25 pin mazda diagnostic connector, with the Fly by wire Zexel injection pump system NP-VE4, the crankshaft pulley split in two, and the outer part moved backwards and damaged the crankshaft sensor.
The pick still ran ok 80% so it was 8 months before I replaced the crankshaft sensor, after doing so, something is not right, and after starting it back up it is somehow out of timing.
https://www.youtube.com/watch?v=eoYXrLOBgxM
The mechanical advice given to me was that it may be a faulty TCV as this was closed for 8 months prior to the new CKP sensor being fitted.
Unfortunately my curiousity got the better of me, and I disconnected the wiring to the TCV and restarted the pick up, it then cut out after about 10 seconds and has not re-started since.
Other advice was…..the engine has been rotated after the crank pulley was removed, and this has put out the mechanical timing? and the other is I have put the timing fip wheel on the back of the new crank pulley in the wrong place?
All I really know is it ran okish without the crankshaft sensor, and even when I restarted it and the timing was out, after the disconnecting the new CKP sensor instead of running how it was, it stayed the same as with the new senso on.
I bought this vehicle new in 2004, only covered 50000 miles…need help to sort this out.
best

Hi got a ford ranger pick up fly by wire ve pump on it. It just cut out and glow plug light flashing I’ve put a direct feed from battery to stop solinoid and cranked it should this give me fuel to injectors as I’m not getting fuel out. I’ve checked stop solinoid and it is working. Could any of the other electrics on the pump stop the fuel being pumped out injectors. Had diagnostic done po251 injector pump metering control comes up. I had just changed the filter on this as it was not running right the filter was full of shite and water when I changed it. I drove about 3 miles with new filter it was running perfect then just stopped. Fuel is getting through the pump and have bled all air out just won’t give fuel to injectors I’m suspecting water damage. Any ideas.
Hi Alistair,
Thank you for contacting us sorry to hear you are having problems.
Water and debris in your filter is not a good sign it could have made its way through to the fuel pump, there is an electronic top called a Governor which can become faulty due to contamination.
There are also other electronics on the pump for example: Timing control valve & Timing piston sensor.
Ideally I would suggest that you get the pump checked and tested along with the injectors.
Feel free to call our workshop on 01509 633315 they will be happy to help.
Hi,
Ive recently been having a lot of trouble with renault clio 1.5 dci. First of all injector 4 was below minimum threshold, but ignored it for a while. Until one the engine stop light started flashing and it cut out, on starting it back up it chucked out lots of black smoke and wouldnt rev over 2k. Replaced the injector but had to drill out due to being siezed since then its had a new head gasket, turbo and fuel filter.
The problem now is that it will only start with easy start, when starting without it runs for a couple of seconds and then dies. 2 faults codes that are present on my scanner are df002 and df132.
Any help would be greatly appreciated, thanks
Chris
Hi Chris,
Thank you for contacting us.
The problems you are having sounds like this could be down to high back leak on the injectors.
We are able to test the injectors out of the vehicle on our test bench, this will show any faults with them.
Feel free to contact our workshop on 01509 633315 and they will be happy to help.
Recently had camshaft sensor code come up so upgraded to a 12v as told to do from ford expert and from most forums to do but did not change wiring connector if that matters i dont know. Sensor apparently a common fault on the focus tdci 1.8 2003 model. i now have p0251 come up few days later p1211 injector type related codes.. Car starts still and is still running ok 60 mpg guessing car is running on constant limp mode i dont know just driving and changing at very slows revs and seem to be getting around ok
Many thanks
Sam Brading
Hi Sam,
Thank you for contacting us.
Those two codes that you have relate to Rail pressure monitoring fault.
This could be fuel pump or the injectors.
We would advise that the vehicle is diagnosed.
Feel free to call our workshop on 01509 633315 they will be happy to help.

Hi,
Are you able to test a set of Bosch Peugeot 2.0 HDI injectors (Bosch Part No 0445 110 076) off the car? I bought a used set but would like to test them before fitting for peace of mind?
Thanks,
Tom
Hi Tom,
Thank you for contacting us.
Yes we are able to test those injectors out of the vehicle.
They will be placed on our test bench and ran through a full test plan procedure.
The cost of the test is £20 + Vat per injector and this takes around an hour to complete and we will supply you with full test printouts.
If for some reason they do not meet the specified criteria then we also have the facilities to repair or supply exchange.
Feel free to call our workshop on 01509 633315 to arrange a time that’s convenient for you.
Hi Nathan,
Thanks for the advice. The car is going in tomorrow and I will pass on your comments.
If the fault is still not cured when I get it back I will contact yourselves for you to have a look at it, as I don’t live to far away from you.
Kind regards,
Paul
Hi Paul,
Glad we could offer you some advice.

Hi Expert,
I have a early 2008 Mazda 3 TS2 diesel and have an intermittent fault.
Initially the engine would cut out shortly after starting when at low revs at a junction or roundabout. When it did so I turned the ignition key and she started. She would then run without any problems. This has subsequently changed, when she now cuts out it takes approximately 15 minutes (sometimes longer) for her to start up. Again when she starts she runs very well. The cutting out usually happens when she has started from cold although it happened once after I had driven for 20 plus miles, again at low revs.
The last time the fault occurred was two weeks ago and it took a lot longer than 15 minutes for the car to start.
Usually the time between the fault occurring is in the region of a week.
I have taken the car to my Mazda dealer and to an independant garage neither of which can determine the cause of the fault.
The car has done 55000 miles, when she cuts out there is no fault light illuminated on the dash and as far as I am aware no excessive smoke. She was serviced in November by the Mazda dealership and the fault started shortly after that.
Any help you can offer will be greatly appreciated.
Kind regards,
Paul
Hi Paul,
Thank you for contacting us.
This problem could possibly due to a faulty Suction Control Valve (SCV) that is situated on the back of your diesel pump.
Alternatively it could be due to a faulty injector causing your fuel rail to lose its pressure and shut down the vehicle.
Feel free to call our workshop on 01509 633315
Hi Paul/Experts,
I’ve a Mazda 3 diesel (55,000 mls) and experiencing similar problems to paul – did the SCV resolve yours? Mine has been occasionally reluctant to start for about a year now; more recently started to cut out, v occasionally, usu at speed bumps – then last week engine has cut out entirely and refused to start at all – RAC tow-away! mazda garage and independent garage failed to find fault; some indication of low pressure on diagnostic, but nothing specific. Fault is intermittant and otherwise it runs v sweetly.
Any advice please and wil it cost arm and leg??
Hi Jude,
Thank you for contacting us.
We had another Mazda 3 in recently with the same symptoms as yours.
We found that to be the fuel rail pressure sensor wiring/plug to be faulty.
This could be the cause of your fault as you mentioned it happens when you go over speed bumps.
Feel free to call our workshop on 01509 633315, they will be more than happy to help.
Hi Guys
I have a 55 plate kia sorrento 2.5 diesel with 24000 miles on clock.
The problem i have is that it keeps cutting out,and it is instant just like turning the ign off, but it allways restarts after about 15/20 seconds. There is no pattern to this at all it might do it after 12 miles or 212 miles at any speed or condition the only time it seem to be worse was when i tryed towing my caravan (scary) i had to cancell holliday then it hapend about 5 times in about 30miles.when this problem started about the secound or third time the warning light came on,so i thought the kia main dealer would be able to read the code and sort the problem (wrong) they said it was reading 2 codes p1693 & p1188 they said the fuel pressure was wrong and the first place to look was the fuel filter, whitch they showed me & it was dirty so they replaced it, they allso sugested the fuel pump could be faulty (low pressure in tank pump) since the fuel filter did not cure it i then had the pump replaced still no good, so they had it back in again this time they said a fulty wiring multy plug whitch they repaired still no good. somebody sugested cranshaft sensor so i replaced it and guess what yep sill no good. it has now been sugested it could be fuel rail pressure sensor ??. i have now spent over £500 and got no results & that is main dealer, i cant afford to take it back and keep trying these things.Because it is not showing any fault codes & you cant get it to stop on camand every body is just guessing ?.Can you please Help as i dont know were to go from here.(ps sorry for going on but i wanted to give you all the info). Thanks Dave
Hi Dave,
I am sorry to hear that you have been passed from pillar to post, spent a substantial amount of money and yet you still have no cure for your vehicle.
There are still many reasons why you have this intermittent problem:
– Faulty wiring between ECU + Pump/Injectors
– Faulty ECU itself.
– High Pressure Fuel pump on the engine could be drawing air into the system.
– Faulty injectors not fueling correctly / Faulty solenoids on the top of the injectors.
These are just a few of the problems that may be causing your fault. Unfortunately it is hard to diagnose without seeing the vehicle.
If you wish to book your vehicle in please call our workshop on 01509 633315.
I have a 1999 isuzu trooper 3.0. Recently it has become much harder to start and is quite smokey for about 30 seconds. A couple of quick revs seems to clear most of the smoke. Is this something that might be diagnosable?
Hi Richard,
We would need a few more details about the vehicle, i.e what system it’s running Denso, Bosch or Delphi.
It would be something we are able to look at in our workshop and possibly get a diagnosis for you.
Please contact our workshop on 01509 633315
hi do you think if i have my fuel injectors tested that i might cure my problem of haveing blue smoke and a smell of fuel when im ticking over as my transit van is a icecream van ive had my van worked on to try and sort this problem but still no look i was told that i needed to get the bores deglazed which i did but still no good your help will be appreciated thanks glyn
hi i have a 1995 ford transit blowing blue smoke and smells of fuel ,i had work done on engine to try and stop this had new valve seals and deglazed bors and a few other bits replaced but still got problem do you think its injector problem thanks glyn
Hi Glyn,
Sorry to hear that you’ve had all that work done and still have a problem.
Usually blue smoke is down to burning oil which could be down to a number of things on your vehicle.
We can test your injectors but its unlikely that testing them would cure your problem.
Feel free to call our workshop 01509 633315.
Hi
I have a 56 plate 2.0 mazda 6 diesel. My main problem is when driving at 60ish and the engine is warm if I gently push down on the accelerator the car judders and I have to press harder on the accelerator to push through the juddering. This happens most in 5th and 6th gear. Sounds like a fuel pump/SCV problem? Your thoughts please!!!
Hi Dave,
Yes your problem could be down to the SCV in the back of your pump.
I would suggest you get the vehicle diagnosed at a diesel specialist so that you have a definite answer.
Feel free to call our workshop – 01509 633315.
Hi,
I have Mitsubishi Pajero Di-D which is giving me problems with starting. It has extreme hard start. I have no idea what the problem is.
Recently I replaced the original injector pump with a second hand one after it packed up. Initially I experienced some hard start but it got worse with time.
Reply
Cheers
Ian.
Hi Ian,
Firstly we don’t recommend that you replace a pump with a second hand unit as you have no idea what condition the pump is in.
Your hard starting problems could be down to electrics on your pump. But without a strip and test of your existing pump we can’t give you a definitive answer.
Please call our workshop (01509 633315) if you’d like to arrange for us to take a look at the pump.
Hi,
I have a 2002 Fiesta Zetec 1.4 TDCI.
Recently it has lost a lot of power. It is pulls away slowly even though my foot is flat on the floor. It is also struggles to maintain 70mph in 5th gear – if there is even a slight incline I have to drop it into 4th.
I’ve taken it to my local garage who couldn’t diagnose any problems, although they said they didn’t have the right equipment for diesels. They replaced the fuel filter but this hasn’t made any difference.
Any ideas?
Cheers,
Andy
Hi Andy,
Unfortunately there could be a variety of reasons why you have the lack of power, and you will need someone who has the necessary vehicle diagnostic equipment to plug into the OBD (on board diagnostic) port on the car to determine the exact cause of the problem. If you are within striking distance of Loughborough we’d be happy to take a look at it for you, as we have all of the kit needed for this type of job
If not, you really need to consult a garage specialising in diesels to ensure you get the correct diagnosis
Hope this helps
i have a mazda 6 2.0 diesel on an 05 plate
mil has lit up and im getting an obdii code p1190 calibration resistor out of range
any ideas?
Hi Mark,
There are 3 possible causes for this fault code:-
• A connector or resistor burnt out or faulty
• A fault in the wiring harness between each cylinder
• An open circuit/short in the wiring leading to injectors
We very much hope this helps and if you are not too far from us we would be happy to have a look for you. Initial Diagnosis fee is £35 + Vat
hi. I have a mazda 6 sport diesel (2004) and I also think my problem could be the scv. I have the stalling problem for about 6 mobths now. at the beginning the engine died when it was cold, it was easy to restart. after a while it started sometimes to stall even when the engine was warm (altough this didn’t happen too often). until yesterday my main problem was the cold stalling but it was easy (most of the times) to restart. since then, the engine stalls almost all the time if I don’t push the acceleration and the big problem is hat it won’t start at all. otherwise the car is running good if I keep the revs up. could my problem be the scv?
thank you
regards,
szabi
Hi Szabolcs,
Yes the SCV could be your problem, but to be sure it would be advisable to have the vehicle diagnosed so that you have a definitive answer on what the cause of the problem is. We are more than happy for you to bring the vehicle into us for a diagnosis; this costs £35 + VAT. Failing that as an option for you, we can supply you with the part to be fitted locally at a cost of £124.90 + VAT.
N.B although changing the SCV is a fairly painless procedure, sometimes they require a “pump relearn” this is needed if the pump does not recognize the new valve.

Mazda diesel stalling
Good Afternoon
I have a five year old 2.0 Diesel Mazda 6 TS and I have recently noticed (last two days) that the vehicle has frequently started to stall. The engine cuts out with warning lights which all extinguish on a restart.
This stalling occurs when slowing down from motorway speeds to relative stop. It stalled 8 times this morning but it also restarts every time. I have not noticed any change in starting the vehicle.
There is lots of chatter on the web about a fault with the Denson Fuel Pump. Is this something you can diagnose – Loughborough is about 90 mins drive from my house so happy to bring the vehicle in unless you know somewhere closer to PE19
Kind regards
Duncan
Hi Duncan,
We have a lot of customers coming in with Mazda 6’s with Denso pumps fitted, mostly suffering from SCV (suction control valve) faults. We have heard of some repairers recommending entire pump replacement but in most cases this isn’t necessary. We can either send you the SCV to have fitted locally or please feel free to bring the car into us and we will be happy to diagnose the fault for you and effect a repair
Please e-mail workshop@ttauto.co.uk to book in your vehicle

Hi i haveb a Mazda 6 ts2 2.0 2006 and i believe that the scv might be faulty. As of the cold weather it always stalls till the engine has been warmed up and it cant keep the revs. Plus when i unplugged the scv it started 1st time and revs where perfect so im kinda guessing that this may be the problem. Was wondering how much it would cost for a new 1 and is there any other way testing this as i havent really got the money too spend if this isnt the problem when replacing new 1.
Regards Scott
Hi Scott,
The SCV is a common fault on these but you need to be able to have the vehicle plugged into some diagnostic kit to be sure. If you are able to get the vehicle to Loughborough we will charge £35 plus vat to diagnose the vehicle, alternatively it may be worth getting the vehicle to another diesel specialist/ quality garage to diagnose the fault for you
We can supply the SCV to you, it retails at @ £136 plus vat
