Asked by Mark Sep 07, 2020 at 12:04 PM about the Jeep Wrangler

Question type: Maintenance & Repair

I have a 1990 Jeep Wrangler YJ that started out by not starting intermittently.
Sometimes it would, sometimes it wouldn’t. When I wouldn’t start, it wouldn’t
even fire. I replaced the battery, the distributor, the plug wires, the coil, the
pcm, and I still won’t start. It’s getting gas, but no spark. I’m at a loss, what
next ? I can’t find a crank sensor, and the coil get 12v with the ignition switch
in. I even cleaned up some grounds ? What’s next

Dumb question, but are the plugs bad? Doubtful they all are, but just thought I'd ask. Sounds like you've covered all the other bases.

Sounds like it *might* be the crank position sensor, though. It's in the bellhousing.
