Shut the car down normal and next morning it would not start. Changed Fuel pump, nothing. Changed ASD relay, nothing. Changed fuel pressure regulator and again nothing. Powered fuel pump direct from battery and it pumped just fine. It would start and run ok when pump was powered direct. Under normal conditions it seems that the pump is not getting the message. Also ran continuity checks and all checked out ok. Is the computer involved in the loop?
