1998 explore will not start when hot will turn over sputter and die, after 15 mintes it will start right up that was last monday when it was 80 outside it now colder outside has not done it again, the only thing i have seen that temp gage is not going past cold never getting to center it will try and drop back down
These symptoms would also be somewhat consistent with a failing fuel pump (fails to start or stalls when hot). What are the chances you have a fuel pressure tester?

How could I have missed such a simple ,, Yes! maybe just getting too old for this ... Philip
I do not have fuel pressure tester also it been a week and has not repeat problem it been starting every time, the day it did it was 80 out it right now it 40
I had a Ranger with an issue that when it got up to 80 outside or so, it would die, and not restart. I would usually wait an hour or more, then it would fire up. I got the codes checked and it was the Fuel Pump Circuit Open/ CPU to Ground code (what ever that meant)!
Needless to say, no fuel pressure (using a pen, I opened the pressure relief valve when it died and didnt even get a puff). I replaced the fuel pump, sending unit, filter, inertia switch, all relays, pressure regulator, and installed additional grounding cables to the engine bay, and still got no where. I finally sent the truck off to the junk yard.
I am really curious to see what comes out of this with your issue!

That sounds like an issue with the driver in the PCM, probably a blown transistor. A new or rebuilt PCM probably would have fixed the issue after you replaced all the other parts. Likely the pump or wiring issue caused the transistor to blow.

Good to know! Unfortunately when I posted the problem many months ago, it was baffling to many, so I figured it was time to call it a wash..
I appreciate the updates! I do not like any problem getting the best of me! LOL
