Mostly on very hot,(Florida), days, after driving 10 - 20 miles, stop & Start, running errands the car is parked for a few hours.
When starting again, the engine turns over nicely, but never starts.
After about 12 - 20 hours just sitting, the engine starts nicely; and the problem is gone. Until the next time).
IO can never get the car to the mechanic before it starts runniung again- so he has nothing to look at.

HELP!

Trust me. If somebody provides a solution that works, I will contribute $50.00.

Next time it refuses to start don't wait for nothing do below immediately to catch it -If its fuel or spark problem and get back with me asap

does it have spark when you pull a plug wire and ground it to the block when cranking? What is the actual fuel pressure on the fuel rail when using a fuel pressure gauge?
