I have an 85 CJ-7 with an AMC 360 with a GM HEI distributor. My problem started a few months ago. The Jeep would just die while driving down the road. It's getting fuel, and power to the coil. The problem has gotten progressively worse. It's now to the point that the Jeep dies almost immediately after start up. It always restarts without a problem, but won't stay running. When I could drive it, I would just turn off the ignition, then back on, and it would run for a while. I have already replaced the coil and the ignition switch, without any luck. HELP!!!

Here's a word that you're going to hate to hear but it'll save you worlds of time in the long run.......GROUNDS.

CJ's are notoriously bad for having poor grounds over time. If a ground disconnected it could certainly kill the engine. I'd make doubly sure you've got a good ground going from the battery to the block, from the block to the frame, and from the frame to the body. Its VERY important to have good grounds.

I'm sure this is the advice you already assumed would come so there it is.

I'd guess ignition switch. Runs in start, not in run.

I've already tracked down the grounds and they appear okay. Have replaced ground cable and ignition switch. I was wondering if anyone has had the same problem with a GM HEI distributor. I'm thinking my problem might be there.

Might check the insides of the dist. Module contact to base and screws along with other connections. If there is corrosion, clean it off good. Maybe replace screws and smear a thin layer of dilectric grease between module and base. [img]images/graemlins/grin.gif[/img]

I had a problem with my '84 where it would cut out on left hand turns. It turns out that there was some wire lacking insulation that would short every time I turned. I finally found the problem when the wires caught fire. If nothing else pans out, you might check your wiring.

Replaced my ignition module (under the rotor) tonight and that was the problem. Thanks for the suggestions.
