I have a 22 inch light bar that's mounted on the nudge bar (been there awhile) and wire fly screen covering the bottom part of the radiator grill, also been there awhile.

Do you have any accessories on the front of the car, or in the engine bay that could reduce airflow around the fuel components? Have you rerouted fuel lines at all?

It may be as easy as insulating or rerouting fuel lines, pretty easy to experiment with.

It may be worthwhile removing these parts temporarily to see if it helps the situation. Often it doesn't take much to change the cooling performance of the car or in your case reduced airflow through the engine bay to keep some other components cool.

Cheap and possibly easy to try this than to keep trowing parts at it.

Also if there is anything new or changed inside the engine compartment experiment with these items too.

Just read in another WJ post about a v8 that had what sounds like similar issues. He eventually, after doing nearly everything I've done, found it to be the MAP sensor.
Does this sound plausible?

Did you ever get to the bottom of this problem?

My diesel WJ appears to have a similar problem.
At first it was only refusing to start when hot.
But the motor just died while in-flight yesterday. It ran fine when I tried again once it was cold. Would be dangerous on the highway - fortunately I was in the shopping centre car park and could pull up in a parking bay.

This also happened to me couple of days ago, stall while driving. Had just replaced injector thinking I would fix this problem. Anyway, stalled on a roundabout, RACV roadside assist came, had a quick look and said had no idea. I got him to use his scanner to check for any codes, none. Got jeep towed home, two days later, it starts first go, runs no probs. So it must be issue when hot.
I am going to buy another wj 4.0L tomorrow, I am done with the diesels for the moment. If anyone wants it, I will sell it very cheap, located Traralgon VIC

Generic scan tools usually don't reliably detect error codes on the 2.7 CRD. Only the Chrysler DRB111, the JeepsWJ software or (I think) some high-end SnapOn tools work.
