TDCI 130 Fuel Pump Change - Difficulty, Tools, Cost
Posted 21 June 2009 - 08:41 PM
Engine just cut out while driving, no warning, diagnosis reveals:
No spray from injectors when loosened on tickover.
TCDI so no primer pump, only likely fault is rail pressure sensor or high pressure pump.
Fault code just low pressure on rail.
Could be sensor but unlikely the fault and looks costly (replace whole rail).
1) Any other tests to confirm fault?
My guess is I need to buy new pump so...
2) Any idea of cost? Any issues with non Ford parts?
3) Is it a driveway job? Any idea how long it'll take an average DIY'er?
4) Can I get away without the special alignment tool (60-80 quid from look of it), and just bodge it on without any risk (my understanding is timing is not a consideration with TDCI because it's electronic).
Thanks in advance.

P0190 Fuel Rail Sensorial Pressure Circuit Malfunction
P2291 inj pressure too low (cranking)
Thing is, with injector nut loosened there's nothing coming out, so I'm a bit confused if it's because the pump has died (i.e. rail holds pressure regardless of faulty rail sensor), or if a faulty rail sensor would cut off pressure from the pump (seems unlikely as its mechanical, although I dont know if there's an electronic regulator valve in there somewhere).
Still, any advice / ideas welcome !! I'm thinking the 1000+ to change pump isnt worth the 3000 value of the whole car.

The fuel filter isn't blocked is it?

I was under the impression you had to buy a whole new rail not just the rail pressure sensor? Either way, no I dont know anyone with a similar car and quite an expensive gamble
According to the guide, when the rail sensor is disconnected the car should just ignore it and start anyhow, raising pressure steadily (i.e. dont leave it running). It wouldnt start when the sensor was disconnected, and no fuel came out of the loosened injector nut (i.e. no high pressure).

From your experience, what's the likely cost of getting this fixed? I can DIY whatever's necessary, take to a specialist or get fraud to take a look.
Deffo no fuel getting to rail, a loosened nut on injector doesnt leak a think on cranking. Is it highly likely injectors are knackered too?
From what I've seen:
~1000 for fraud to fix the fuel pump (includes changing the lines around pump also).
650 for a brand new pump with lines, not found a better price for new.
~200 for a set of injectors from someone off the board here.
I dont have the Â£70 tools to remove pump if I DIY, but do have odb software to code injectors if I DIY those.
at ~84k the car is probably due for new clutch soon, and needs a service and a few small things done anyhow.
