3.0 won't start when hot
2001 3.0 When running a/c and truck is up to normal operating temperature if you shut it off, sometimes it won't start. Turns over, just won't fire. Let it set for anywhere from 30 min. to a couple of hours and it starts right up. Doesn't do this in cold weather.
Recently had plugs, wires, coil (or coils, I didn't do it) replaced and computer updated. Since then, isn't as frequent, but still does it. Once it fires, there's no "check engine" light or any tell tale signs of a problem.
