Re: fuel delivery problem

Empty tank.
Blown fuse.
Open power supply wire in harness.
Open ground wire/circuit at fuel pump assembly/tank.
Sunken socket in connector(s).
No power to relay due to broken wire or bad driver in ECM.
Fusible link at starter solenoid stud burnt/broken.

Fuel pump should come ON for two seconds when ign ke is turned to IGN position. After this event, Start signal should energize the relay, via ECM, and, in a parallel path, oil pressure switch should close and provide another path to energize fuel pump. Oil pressure sensor is underneath distributor.

Re: fuel delivery problem

i heard that if my oil pressure sensor was faulty that my fuel pump would not energize. is that true?
