Intermittent hot start issue

[lfhoward]

My Jeep is starting to develop a crank no start issue when the engine is hot, like if I’ve been driving, go into a store, then come back out and try to start the engine. It’s fine 9 times out of 10, but it happened twice last weekend and I think the frequency of the problem is increasing. Waiting 10 minutes or trying to start it several times in a row has always worked, but I don’t want my wife or me to be stranded when something eventually goes kaput.

Some background:
- The engine runs very smoothly, no codes, no pending codes, no misfires
- NGK copper spark plugs, only 20K miles on them since I changed them
- All coils and injectors are original (175K)
- Fuel pump is original.
- Engine is newer (only 89K)

Has a hot start issue happened to anyone else? What was the culprit?

Yes no one wants to be stuck out there. Could this be electrical or fuel pressure related?
Just for curiosity, next time it does this, remove the gas cap for a few seconds, then replace it, wonder if that may help or not..
You could call a dealer and ask them if there are any "known issues" related to this intermittent hot start issue...
