Electrical 79 CJ5 258 no spark

[TimmyCJ5]

I have a 79 CJ5 AMC 258 i6 / 4.2l that the engine would not shut off when the key was put in the off position. It was sporadic and didn’t happen every time it was run. I replaced the key ignition cylinder, ignition module, coil, plug wires. I bought a new distributor, but don’t want to replace if it’s not necessary. Is there any wiring I can check, does the connection on the steering column cause issues. What about the connection on the connection on the firewall. The tub was replaced with a fiberglass one.
