Completely stumped.
so I rolled my jeep and it ran afterwards. I drove it to a shop and it started getting less and less power and then I left it at the shop. They didn't want to touch it and when I got it back it wouldn't start. I found out that the shaft under the rotor bug in the distributor snapped. So I replaced the distributor and my timing is right. I'm getting fuel and spark. I can get it to fire but it won't idle. Any ideas?

Double check yourself first.
Setting Your 4.0 at #1 TDC
With #1 spark plug removed, turn the engine over clockwise using the 3/4" front crankshaft bolt. You will see the degree marks on your front cover. Mark the 0 with chalk or white-out.You will see the timing mark on the balancer. Mark it with chalk or white-out. While turning the engine over, put your finger/thumb over #1 spark plug hole. As the mark on the balancer approaches the marks on the front cover, if you are coming up on #1 TDC, pressure in the cylinder will push on your finger. If there's no pressure, you're at #6 TDC and need to crank the engine over until you see the marks coming together and you get pressure. Set the mark on the balancer to the 0 mark on the front cover.

I set it at top dead center, I checked the compression and it's not showing any other signs of a cracked block. someone told me they thought it would be the distributor broke off but I don't think that's it.
