Help needed asap. TJ will not start

OK, so I got into the jeep this morning, and she REFUSED to start, or even attempt to. Since it is a manual, I pop start it down my hill, and drive over to store to look for some things, thinking it was a dead battery. I get to the store, I shut the car off, try to start it again, she fires up. I get what I need from the store, and try to start her again, nothing. I pop start it, and limp her home. I checked the spark plugs because I read somewhere that might have something to do with it, and didn't do anything. It actually may have made it worse because now when I pop started it to get out of the garage, it idols very poorly and wants to stall. I'm going to try a new ignition switch tomorrow. Any other advice would be much appreciated.

Two of my Jeeps did that when the battery was bad.

I'd say either the battery terminals aren't tight to the posts/have corrosion or the battery is bad. I had one on our TJ act up yet when tested, it was 'good'. After it was tested, I still couldn't start it. Being that I was stranded at O'reilly Auto and jumping it didn't work, I figured I may as well try a new battery. That did the trick.

I don't think its the battery. I have radio, dome light, and the lights on the dash don't dim when I try to start it. I think it might be the ignition switch or the starter solenoid.

Could also be the ignition actuator pin has broke. Here is a thread for replacing it.

Had the same thing just happen to me. I took the column apart and the plug for the ignition switch was not making good contact. Wiggled it while trying to start it and it fired up. If you can feel the spring when you turn it to start the ignition switch is prob still good. The yellow wire coming out of the ignition plug is the start wire. I would test that wire and see if your getting fire there. If not its prob the ignition. From there the yellow wire goes to the clutch cut off and comes out yellow with a red stripe. You can unplug it and make a small jumper wire to go between the terminals.

Neither did mine.

Start simple. Have the battery checked. It's fast and easy and worst case eliminates the obvious. If the battery is ok, it's on to connections. Clean them up and make sure your grounds are good. Again, 10 minutes of effort.

If nothing show up there then it's time to move onto the next possibility.

I changed the ignition switch, and got nothing. It has power going to the starter relay, but no power to that starter motor. Any idea how to test if there is power going to the starter motor?

You should get 12v between the solenoid (positive terminal) and ground when the key is in the start position.

If you have power to the solenoid and it is functioning properly you will hear a click (or series of rapid clicks) when you turn the key. If no click and you have verified good power to the terminal then the solenoid is likely bad.

Take the starter off and have it tested at the auto parts store.

I tested the starter and it passed with flying colors. Any other ideas? I'm thinking it's a short after the starter relay.

Took it off, and had Advanced Auto check it on their machine. When I got home and put it back on, with the new ignition switch, old one failed, and new ignition actuator pin, it fired right up. She now runs as good as the day I bought her.

You may want to consider doing some of the "dirty dozen" checking ALL the ground points in the engine can't hurt.
