Hey there everyone!
I just picked up a "new" 1982 CJ7 with the 258 I6. i got the motor cranking, but there was no spark from the ignition coil to the distributor cap. I had the same problem in my yj and i had to replace the coil and the ignition control module and that solved the problem. So of course i went down the same route, and it has not solved the problem. Now i am thinking it might be an electrical issue, possibly with the starter solenoid? This is a project, so i figured i'd get some other opinions before i throw some more parts at it.
