I have an 86 cj7. It has a weber carb, and a new motor(258). I have replaced the distributor, the distributor button, the ignition coil, and the ignition module.
A week and a half ago I got in my jeep and might not have let it warm up ad long as I should have. She made it around a mile before she shut off going down the road. Once she stopped, she would only turn over. I have tested for spark and have gotten nothing.
I started doing the nutter bypass, but stopped after splicing the wires because I started to reAd that it was for the original Carter carb. Thoughts on if this would work?
Also, since I have started fixing her, or throwing my money down the drain, I've noticed my radio won't turn on. That was until I was messing with my fuses and tested my lights. I realized that the rAdio now only works when the headlight dimmer is on.
The fuel pump is working. Anything else that will help with a diagnosis, please let me know.
Sounds like a classic loss of ground problem. Mine died at a red light and I threw new parts at it and finally found the ground on engine block fro battery appeared to be tight, I removed and cleaned and scratched it up and tightened it to finally fix the problem.
I did the test and got to step 8 where I was told the problem was indeed a ground, or at least that's where it's leading me. You mentioned some wires to check, you wouldn't have a better description or perhaps some pictures?

The negative terminal of your battery should have two wires coming from it. One goes to the engine block and one gets attached to the firewall within a few inches of the battery negative terminal.
it's important that not only the ground wires are there but they have good contact including the connection to the battery itself. Undo the ground connections at the battery, engine, elsewhere, etc. and make sure the wire terminals are clean, the connection points are clean then re-attach and make sure they are nice and tight. It's hard to tell if a connection is good just by looking at it so this is something you can do that won't cost you any $$
When I was following the diagnostics test, it said that the negative on the coil wasn't grounded. Is there away to test that? I am thinking that a wire from the negative terminal of the battery to the negative on the coil will work?
