Thanks for all replies, sorry Mark I tried to do this from memory I code read this at work but posted from home, thought I may have got code wrong, but I do know it was a glow plug related code.
There is no fuel at the injectors, I bypassed the filter with a can of fuel and a hand pump from a peugeot,still no fuel at injector.
Kieth, the fact that this runs on easy start I felt was worth mentioning as it demonstrates that it is reasonably mechanically sound, perhaps you disagree with this method?
Tony, This van has a pump ecu but previous garage had fitted a new one I did check inside the old one they gave me and by appearances is ok, I retried this unit with new crank sensor in case new one needed codeing to car, still no workee.
Thanks for all these replies, (still must buy a scope!)
Cheers Phil
