HELP! Jeep won't start

This has me stumped. I get one single click when I turn the key. Starter and battery test good. Terminals cleaned, ground connection checked, no codes thrown.

This has happened 3 times. It might be a coincidence, but it was freaking COLD all 3 times. Each time, I messed with it and it eventually started. First time it went 2 weeks without the problem coming back. Yesterday it happened again. |Had starter tested and re-installed. It started but is doing it again today.

'05 Wrangler X 4.0 manual

Any ideas?

I've heard that some places don't test the starter properly as it should be tested under a load...and many places don't test under a load. I've also heard that a single click is often related to a solenoid or something for the starter sticking. I've never really messed with the starting system on a Jeep so i apologize for not being able to go into detail. This happens on our Chevy dump truck at work frequently and since I've been too lazy to take it to the service department, the easiest way to get it to start is to just keep turning the key back and forth to the start position until the starter kicks.

Also when you cleaned the terminals, did you disconnect them and clean the entire posts and inside of terminals with a wire brush post cleaner as well?

Have you tried to jump it and does it start/try to start then or do you still get the single click?

Terminals and posts were cleaned very good. Put charger on it and it showed battery was fully charged. Even on "fast start" setting, still got single click.

I watched them test the starter. I seriously doubt that it was with load. I've been wondering about that. Autozone ain't the best. Thinking of taking it to Napa.

I had the starter tested again. It passed, but I replaced it anyway. The Jeep started with no problem. I'd like to say I think it's fixed, but I don't know. This is the third time I've got it to work. First part I've replaced, so I guess I'll find out in the next 2 weeks whether it was the problem or not.

Best to test with a load meter in vehicle off the battery when starting engine to get true starter amp draw.

I have a similar problem. My jeep was sitting for about 2 weeks, I tries starting but it woundn't turn over. Every time I let go of the key it woud stop trying to turn over completelly. I founf myself holding the key in the run position almost forcing it to run or turn over. Eventually after about a half hour it turned over. I let it run for a while it was good, but never drove it. I tried a few days later and got nothing. Just some clicking by the starter relay box but not even a click to the staarter. I replaced the battery, starter, and starter relay...and still got nothing. ANY IDEAS???

alarm system?
do you have to hold the key to run the car, or it will cut off all systems?
will the key bounce back towards you when you let go, and the jeep will shut down?
it may be your key port, or some wiring in your steering column. pop off the dash and look for any shorted or fouled wiring. if you have access to a voltmeter, test the wires you see for voltage. if you have an alarm system, make sure it is disabled, and the emergency kill is not engaged, it may be trying to kill your systems.

Doesn't sound like the issue I had. All I got was a single click from the solenoid. The starter never engaged when this happened. Even though the starter tested as good twice, I replaced the rebuilt piece of chinese junk. Haven't had a problem since then.

Your issue sounds different. From what I've read, I'd lean towards the ignition switch, but then again, I'm not exactly an expert.
