First > *TEST* ALL FUSES! .. Fuel pump relay does not 'remain' energized when the key is turned on .. Must have engine 'cranking' signal .. Fuel pump circuits need to be tested while a helper 'cranks' the engine!
Thank you Pushrod for answering, yes fuses are good and the relay does not energize at all, if I energized terminal 5 to 3 while cranking the engine it turns the pump on and so the engine but it turns off if I dis-energized 5 to 3.
Check/test relay wire connections *underneath* fuse/relay box .. Test PCM supplied - relay 'ground' circuit... PCM failures are rare on this vehicle, however anything is possible... Most likely a wiring problem TO the relay .. Good luck with it!
