4.0 V6 This happens after I drive it and get it up to temperature. Then,
when I shut the engine off and try to start it about 5 min. later, it
won't. I've replaced the Egnition Coil, Plugs and Plug Wires. I've heard
that maybe the fuel pump needs to be replaced but it wasn't a professional
opinion. I don't want to spend the money and time trying to repair the
truck again on something that may not be the problem. I need some kind of
definite answer oon what is wrong. Help PLEASE!!

Just a thought - will it start if you push on the gas pedal? If so,
the idle air control valve is the problem.

This problem was talked here previously. The solution is to change the fuel
pump relay. When it get hot it won't start. You can take a look in previous
post in the forum about this issue.
Hope this will work for you.

Thanks for the responses. It was the relay switch!!!!!
When I tapped the switch, the fuel pump would kick on. Now that it's
replaced it works fine. Thanks a lot!

Tough call without some diagnosis. With the radio off, turn the key
"on" & listen for the fuel pump hum. It should run 2-3 seconds & shut
off. You may want to try swapping the fuel pump & heater motor relays
in the under hood relay box. Worst case is you have no heater fan....

Pull a plug wire & check for spark while someone turns the key to
"start". No spark means you need to check further. One possible
problem is a bad crankshaft position sensor that comes open when it
heat soaks from a shut-down engine. Again, without diagnostics it a
shot in the dark.
