Fixed. Came outside this morning and turned the key to “on” and let it sit for 10-15 seconds. Started it. Warmed it for a few minutes. Drove 1.5 miles to the freeway and drove the snot out of it for 15 minutes. Got home and the heaters were ready.

Dealing with the same thing right now on my 2000. I haven’t replaced any sensors yet. I’m hoping that driving it will clear up the issues.

I feel you. I wanted to put a rag in the filler neck and light it. I'm the original owner.This is the first major issue. I'm the only one that's ever been under the hood so the learning experience with OEM parts has been an expensive one.

New crank sensor is in. P300, 303 & 304. Next is gonna be a rag and a match in the fuel tank.

Closest one is Henderson, Nv. Unless I still have my original.

2000 and newer have coil packs and yes it was changed and now the original is back on and still a misfire on 6.

So here is the long version. I was on my way to the desert with my trailer in tow and the Jeep quit on a hill. Got it towed home and replaced the crankshaft position sensor. Nothing. Drained the fuel and replaced the pump. Bingo. Fast forward to last week. The jeep has been sitting. Starting it...
