did you clean the check valve coming out of the ecm? i had this problem. i replaced the fuel separator, changed the fuel lines and found that the fuel runs through the ecm plate , it has a check valve behind the top hose, it was stuck. replaced it and works fine,but i had it in the shop 8 times before i finaly got it fixed.

Throttle pedal wires going through fire wall will have bad contact. Some units have gold pins installed to help. Terminals will look fine but will still lose contact. I have found twisting three new wires and running them straigt to the ecm to the trottle pedal through a hole in the firewall Works fine. I have also seen engine postion sensor working out of its internal holder. Make sure four pin connector dosen't have oil in it. If it does, it is a sign the engine speed sensor needs to be replaced.
