I was driving my Jeep and out of nowhere the engine dies on me. I checked and it had fuel pressure but no spark so I had my brother tow me home so I could work on it in my garage. When I got it home I checked and my plug wires had corrosion on them but the power going to the coil seemed to be intermitent. I pluged the connection back in to the coil and the Jeep started right up, I didn't do anything to fix it so I know the problem will come back but I can't find anything wrong since it starts and runs now. This was at midnight so I haven't had time to replace the plug wires yet but I don't think this is my only problem. Does anyone have any suggestions as to what can be wrong?????????

It could be the plug wires, coil (but I doubt it), or crank sensor, or something in the distributor (I actually had a distributor fall apart on me about 40k ago but I replaced the distributor). Anyone have an educated guess as to what the probable cause is?

 

Had found that the crank sensor goes bad on the 4.0l a lot. My jeep went thru 3 or 4 of them in 150,000 miles.

 

I went through a couple of them on my 89 AND my 94 cherokee 4.0s. Easy fix, if its not that, its good to have a new one anyways. Hope that helps.

Thanks guys, I replaced the cam sensor and it hasn't stalled out yet but if it does I will definately replace the crank sensor.
