I have checked on the scope under driving conditions.
Cam and crank. Lives and Earths. Fuel rail pressure sensor and fuel solenoid. Boost pressure sensor, TPS, CTS, ATS, charging. Injector feed and triggers [amps and voltage]
When the fault ocurres the injectors shut down. At the same time on the 4 channel scope I was watching the fuel pressure sensor and solenoid and these showed no deviation. The fuel pressure slowly dropped as the engine ground to a halt.
With the code P1130 I would have thought I would see a sudden change in the fuel pressure voltage so that the ECU would 'see' a pressure fault occuring. But no matter how many times I check this it is the same every time.
The car is now a our local diesel guy and he has done all the reqular checks to make sure injector bleed off is correct ect.
They now want to take a 'punt' and replace the pump. I am realy reluctant to advice the garage of this due to the high cost, and what I feel in the end could be lots of tears!
I have checked the archives, but found nothing conclusive.
If any one has had any experience with this problem I would love to hear form you.
Regards
Simon

If you post the chassis no or e-mail me the reg no I might be able to check if there's an update available for the Fuel system. I think it's possible given the symptoms and the lack of deviation in the live data.
It might also be worth checking the live data from the crank and cam sensors together. If the cam sensor momentarily fails it can cut the engine out.
