I have a 2001 F150 5.4 Supercrew Lariat. It intermittently after driven somewhere a long enough distance for everything to get up to temp will crank but not start. If I disconnect both battery cables for a few minutes it starts up. I have replaced the PATS transceiver. Any ideas as to what else this could be????

 

I'm having the same issue right now. had to call for a ride left me and my son stranded. Replaced a fuel pump about 100K miles ago. I hear the pump priming when I turn the key but just wont turn over saw another thread regarding the pcm transceiver? any ideas anyone?

 

Won't turn over, or it turns over and won't start? Check the fuel pressure with a gauge, you can "borrow" one from most parts stores, 28 psi minimum.
