i havent a clue

I have a 92 t-bird with the 5.o H.O. engine, The fuel pump went out about 3 months ago so i replaced it and the fuel filter also. My problem is that 3 times in the past two months , i have went to start it and it wont, it turns over fine but acts like its not getting gas but this only lasts for about 2-3 hours then it fires right up like nothing is wrong and runs just fine. It never runs rough like the filter is getting dirty or anything, it doesnt give any warning at all....just wont start.......any ideas?????????

Throttle Position Sensor?

Sounds kinda similar to what happened with my 93 a few weeks ago. I got a new TPS for about 30 bucks from Autozone, and the problem went away.

Have them test if for you before you buy a new one, though. I watched the multimeter as they were doing it on mine, and saw the bad "spot" on it for myself.

Hope this helps.

Codes, Codes, Codes.

Pull the codes, and see what the computer tells you is wrong.

there should be a fuel regulator sensor located in the truck on the drivers side, it should kinda look like a small refrigerator, well, it's shaped like one anyways, that is probably your problem, my t-bird was doing the same thing, i replaced that and it fixed the problem, i ended up replacing 5 fuel pumps in 2 years because of it, i wished i would have known about it sooner, maybe i could have saved my self alot of money

That's not a fuel regulator. It's a fuel pump cutoff switch. The idea behind in it to interrupt electricity to the fuel pump if the vehicle suffers a hard enough impact or rolls over.

But once that impact breaker is tripped, it requires physical contact, by the way of pushing that little red button back down. So, I can't see how his car starts after several hours of sitting there. But again, pull the codes.
