I put a new fuel pump on a drove it 2 days and I am back to it will not start but once in a blue moon.I do not hear the pump
run it is not the relay.I think it is between ignition switch and the fuel pump.I was looking for wiring diagram can it be the
fuel pressure regulator ? or ignition switch ? IF it starts it keeps running .

check your fuel pump to see if it gets power or not.there was aproblem with some of those and anew wiring harness was required and had to be spliced in as it took a different connector. The diagram i'm sending is for fulepump relay check where red wire enters for power as it can be the connector infuse box then check gray wire which leads to tank and make sure that gets power.
