2002 explorer fuel problem

hello all i have a question about a 2002 ford explorer recently sometimes it doesnt start and if i wait a while it usually starts i checked the fuel pressure it was fine but then it was running and i checked a second time and there was barely any pressure and it wouldnt start and it only seems like the fuel pump is turning on when it wants to do you think the fuel pump is going bad? or could it be a relay by the way when it does start it runs perfect like it was brand new so that makes me think it shouldnt be the filter but then again im not a mechanic so if anyone can help PLEASE

Since it's intermittent, it's tough to tell. If you don't hear the pump run, then your problem is fuel related. I'd start by replacing the fuel pump relay. Cheap and easy fix.

before you think of changing out the pump, replace the FPR (relay), they go flakey. It is in the distribution box, engine compartment.

grrr

ok so it ran fine all day yesterday after replacing the fuel pump relay but this morning after i went shopping it wouldnt start again until i let it sit for a while can it be the coil pack getting hot or something else that doesnt want to work when its hot? i was letting it get hot yesterday and it was startig just fine or maybe a loose connection? is there any kinds of test i can run to try to narrow it down to what it can be? i keep starting it now and no problems hot or cold im lost PLEASE help

You have to narrow it down to lack of fuel or spark, I am on the road right now will check in later.
