This may be kinda long, but I want to give as many details as possible.....
87 Laredo 4.0L AW4 NP242
Anyways, few weeks back the jeep began sputtering very badly after it seemed to warm up. I figured it was a fuel filter/distributor cap issue so I replaced both one night. Started up fine the next morning, idled fine, everything seemed ok.
Started driving to work only to find 5 miles away from home it began the same problem, sputtering with a complete loss of power. It was as if the engine completely turned off and back on again as I could completely floor the car and it would randomly go, but lose all power again. This leads me to believe its not a spark/fuel issue as it didn't have the typical symptoms. Once I limped it home, I pulled into the driveway where it promptly died.
I tried restarting the car (where it would previously restart, but idle somewhat rough) and noticed it cranked a little slower than normal, but never actually started up. I cranked for a little bit (less than 8sec) and all the sudden a big cloud of smoke came from the engine bay. I popped the hood, poured water all over the passenger side area to find a single wire completely burned up.
The wire comes from the starter relay and goes to the ballast resistor. I'm dumbfounded as to how this happened, but I have a feeling it is not directly related to my previous issue.
The CPS has never been replaced (to my knowledge) and it is a high altitude version.
Can anyone shed any light on these issues and perhaps give me their take on the situation?
All help is appreciated!
