Yep! Wont start again...
Everything has been replaced on this truck.I mean I got a list and everything I read about my problem Ive replaced.I recently,a few months ago put a new fuel pump in.Has been runnning great till I stopped at a store today and couldnt get it running again.Just for chits n giggles I sprayed some carb cleaner in the throttle body.Sarted right up but died shortly after it used the spray I gave it.Is it possible this pump went out on me also??? BTW I can here it prime up so I know its running.Gonna check filter n pressure again tomorrow.

Yes it could be the pump again, running the gas on E (Empty) will burn it out quickly. Other options is a bad fuel pump relay to bad wiring. Or clogged fuel line. Yes check the pressure and check it while it doesn't start.

Got a ride to my truck this am and got in it started right up!! But,my dumb azz decided to stop at the store on the way home and it wont start again.Happy its not my fuel pump again but what would I look into to find the culprit? I was thinking the coil heating up but not really sure....

Before moving onto spark, you should make sure that your Fuel isn't bad. When it won't start check the fuel pressure, is it good? I know some multi-port engines can be very finicky if they don't receive enough fuel pressure, a bad or failing fuel pressure regulator could be to blame. Check fuel pressure then move onto spark.

I thought we did a lot to our truck but sounds like you did a lot more to yours. That absolutely sux that you have to redo the pump.
Just curious . . . what should the fuel pressure be?

just because the pump doesn't turn on doesn't mean its dead. Put 12 volts to the pump and make sure the ground is good. The auto shutdown relay turns the fuel pump off almost instantly when you turn the key to on if there is a problem elsewhere. No sense buying another fuel pump until you absolutely know that is the problem.
