Hi, I'm currently having a problem with my 2001 mondeo tddi, the problem started one evening driving home when the car decided to cut out, i tried to start the car but just turned over and over and failed to start, I knew these tddi's suffered problems with the electronic lift pump underneath the car so I decided to give that a few hits with the wheel brace and tried to start the car, it fired up straight away but didn't get far down the road before it cut out again, so I got my mate to tow me home, thinking it would be a easy fix and just the lift pump I ordered one, I fitted the pump and it fired up so I left it idle for a while then took it out for a drive unfortunately it kept cutting out again after some deliberation about the new pump I had fitted being noisy and felt as if it was jumping slightly I ordered another more expensive pump I then fitted that one this one sounds much smoother and less noise but the car is still cutting out, I have swapped the fuel lift pump relay for a known good one with still no joy I have also replaced the fuel filter, I plugged it in to see if it picked up any faults and it came up with p1665 (pump communication problem and a crank shaft position sensor fault, the problem I have with this is the fault now is so random and now when it does cut out all I have to do is turn ignition off and back on whilst driving and away it goes again.
Any help will be greatly appreciated.
Cheers,
Rich.
