Ford Transit Connect 1.8 TDCi 2008 - Non runner, code P0087 pressure loss in system - Fixed #

Posted by Terry Taylor on September 4, 2012, 9:57 am

Year of Manufacture *: 2008
Engine Size and Code *: 1800 tdci
( Optional ) Scanner Used: delphi
( Optional) Fault Codes: p0087

Hi

car came into garage has a none runner checked for codes came up with p0087 pressure loss in system carried out back leakage test,checked pressure out of pump no pressure build up checked with local ford dealer,without telling to much they say it may be pump or pcm bring it to workshop,being a siemens vdo pump there his not a lot of info out there so we have decided to remove pump and get it tested this his were the problem lies looked simple at first but there his a chain driving the pump and we are just a bit concerned it may drop off the pump so if anyone has changed the pump we would be most thankful for this info.thanks terry

Hi Terry

There is alot more you can/should check before removing pump.

Has this got an intank pump?

I would think the may be an integral suction pump in the high pressure pump?

You really need to validate the low pressure fuel circuit first.

Maybe for example, if the cranks signal is corrupt or non existent and the ecu didn't think the engine was turning, why would it even try and generate pressure?

What is the FRPS signal reading at KOEO? with a scope or DVOM.

How did you check for pressure at the back of the pump?

I wouldn't want to remove the pump on one of these or any CRD unless I was sure it was the problem.

Agree with James you need to be sure the fuel suppply is o.k, then scope rail pressure sensor and post.

hi spoke to ford technical today pump his suck and blow pump no low pressure pump to check gave seperate fuel supply and it will run,change fuel filter for geniune ford no difference,ford tech say ohms check across i.m.v sensor this his the only test they do there are no values for pwm signal from p.c.m. 4.77ohms to 5.83 anything outside and the imv his kaput.ours was 3ohms.thanks terry

Re: transit connect

Hi Terry

If it will run with a seperate supply then changing the IMV will not fix this vehicle.

You need to check from where you connected your seperate supply back to the tank for a restriction.

Re: transit connect

If it runs with a separate supply an I.M.V will not fix this.

hi if we where to connect a vacum gauge and see what the negative pressure the pump was pulling would anyone know what value we should be seeing.thanks terry

Hi Terry,

Question; If you were to fill a bucket with water and then place a rubber pipe in it and suck the water through the pipe using your mouth, how much effort would you need to put in ?

Then place a pair of mole grips on the pipe and swish the pipe. Now try again to suck the water through the pipe, What happens?

Lastly, drill or cut a small hole in the rubber pipe near the end you are sucking from and then repeat the test once more.

Did you use a pressure supply pump or just connect a pipe from the HP pump into a can of fuel.

Can't you T in a vacuum gauge into your test rig to see what readings you have then compare to that of the car.

When you have a different reading, work back through the pipework and connections to see if you have any leaks. Not sure if its possible but can you pressurise the fuel pipes to see if they leak.

I've done this with a hand primer on a Vauxhall Astra (accidently i must admit) by putting the primer back to front by mistake but this actually shown a pin hole in the pipe quite easily even though the van run with difficult starting fault.

I back fed the fuel filter if this is possible.

I always measure the supply fuel pressure with an inline gauge and cause restrictions to challenge dirrerent parts of the system.

Although, I was curious to see what would happen if I tested it as you say with a dead headed gauge straight on the back of the pump so I did it, on a mitsubishi shogun I was checking the supply on anyway.

It would appear at cranking speed the the gauge goes negative in very tiny increments, but not to its full potential I think due to the rotational speed of the pump.

As Lee said exactly how did you supply the pump with a seperate supply?

Also think about what Mark has said and I am sure everything will become clear.

Hi

Right full storey from customer this vehicle had done the rounds and of course we started looking for a complicated fault we didnt check basics the fuses, the fuse for the imv sensor had blown vehicle was not even trying to inject fuel once we had replaced the fuse then a different tale the vehicle then tried to start, after reading all of your threads and picking the best bits this thing cracked into life so we can only think it was air locked from over cranking??? why the fuse had blown dont know but anyway thanks for all your help

Terry

>>> why the fuse had blown dont know but anyway thanks for all your help <<<

Have you monitored the current flowing through the fuse to see if it is being overloaded?

If it was the IMV at fault puliing too much current
we will never know as it was swapped for a new one.

However if the wiring is chaffed and shorting out it will
surely be back

hi both of you are correct if the vehicle comes back i will repair foc.repair not to standard expected from this great site, thanks again terry (learning all the time)
