Ignition problems- Will not do anything-HELP PLEASE
I am new to the forum and have a 86 cj7 with i-6 258. The jeep has been sitting for over a year while I found some money to get it painted and running. I have most of it done but I am stuck at my ignition problem. When I turn the key the gauges come on but when I turn it to start NOTHING. I have changed the Ignition Module, Ignition Switch (under Dash) & the silinoid. I am out of ideas and do not know where to start testing to find the problem. Thanks for the help in advance.
OH I can bypass the silinoid and it will turn over, and when I loaded it from the paint shop it was running.
I wired it exactly as the old one. Positive lead from Battery on left and lead to starter on right. The 2 small wires are tide together with a rubber grommet thing so they could not be crossed.
I just tested the solinoid and on the battery lead I am getting 12.7 but on the other side with my son turning the key to start 0.00. I guess the question now is what is causing me not to get power through the solinoid?? Just changed it out a couple of hours ago.
Try turning the two wires through 180 degrees, I seem to remember swapping the solinoid on mine and having the same thing, also check the ignition wire from the key to the solinoid as mine was damaged along the bulkhead, ultimately if you can start it by bypassing the solinoid then it sounds like a wiring issue to me

DO NOT jump across the two large terminals on the starter relay.
Jump from the larger battery cable terminal to the small terminal marked 'S' (Start), see if the starter turns the engine.
If it does, you have VERIFIED the starter solenoid is working to turn the starter.
Hook a test light to the other small terminal on the starter relay marked 'I' (Ignition),
And jump the 'S' terminal again.
You should get a 'Bright' light when the starter relay is cranking the engine.
If you don't, the 'I' terminal isn't giving your ignition any current to run the ignition system on during cranking,
And the starter relay is 'Bad'...
Find the small 'Blue' wire going to the starter relay.
Probe it with a test light while someone turns the ignition key.
If you get a 'Bright' light at the 'Blue' wire terminal while the ignition switch is in the 'Start' position,
Then it's working correctly.
If you DO NOT get a bright light when the key switch is in the 'Start' position,
Then you have an issue with the fuse, ignition switch, bulkhead connector, ect.
Do these simple tests and get back with us with results.
Just a Hunch,
Since the vehicle was just painted, if the fire wall was painted, I would have a CLOSE LOOK at the bulkhead connector to make sure it's bolted down securely.
Paint & Body men don't much deal with mechanical things, and the wiring is often overlooked.
I am guessing with the other poster that said the small wire side plug is upside down.
