Hey man. Welcome to the forums. The first thing you have to do is find out what you’re missing when you are having the no start condition. Most likely spark or fuel. I would start by checking fuel pressure (after you have the vehicle to the point where it won’ t start, but just keeps on cranking). Here’s a video.

Here is Eric’s video on no start conditions, and what to check for:

These are just starting points. Use some diagnosis, and narrow down your problem. Good luck, and keep us posted.
Welcome to the forums!
+1 on Beefy’s post.
I would definitely recommend checking or fuel pressure also at KOEO. You may have an issue with your fuel pump check valve, fuel pressure regulator or even your ECT.
We also have a free link to Chilton’s online in the ‘How To’ section that may have the specifications listed for fuel pressure readings.
Keep us updated!
I’ve had a few people ask me about Jeep stalling problems similar to yours and I’ve gotten a few different answers on the ‘fixes’. One of them told me that on some models there was an issue with the throttle body itself and once she changed it out things were good again, she had cleaned it several times before but the only fix was to replace it. I’ve had others tell me about a PCM issue. I would start with the basics as suggested as that is always the best place to start as many automotive problems are simple in nature and we as mechanics tend to complicate them unnecessarily. I’ll also post this link to checking for vacuum leaks that I hope will help.
