OK, well now I am confused. On the trail I crossed the 2 poles on the solenoid and could hear the starter spin but not engage. The key was in the run position. I have done this with vehicles in the past and have had them start. When trying to start the jeep with the key only, all that could be heard was a very faint click at the fuse box. All the fuses seemed to be fine. Also, if crossing the poles on the solenoid caused the starter to spin but not engage, it was getting power from the battery. Anyway after reading the postings above I am curious to see what ends up being the cause of the no starting jeep. Still thinking it is a faulty starter. Trying what Jan said would work though with testing the starter out of the jeep with a battery. Guess I'll have to wait and see what the result is :-) But didn't he switch starters with one known to work? From what I understand a replacement starter was $200 bucks so he was trying to pinpoint the issue. Or I just missread something somewhere and all my previous typing was a waste. lol

All that does is spin the starter motor. need to give the little one 12V. you can do it with one side of the booster cable, batt to little terminal. or starter constant 12V to little terminal w booster. its tough to do the screwdriver trick on the 4.0 starter. That's what I'm picturing you guys did. stick a screwdriver across the 2 big poles and it spins and does nothing. There's ALWAYS next time! lol

I have installed a new solenoid and a starter that is know to run and I still get nothing when I turn the key. It's the same response I got before this happened when I wouldn't press the clutch when starting the jeep. I'm now at a loss as to what could be wrong. Anyone have ideas as to what I can check next? Yeah he switched solenoids and starter. Problem still exists....weird.

nah, that info just isolates the problem as being farther up the line. The 12V solenoid isn't energizing for whatever reason.

I guess you didn't mean the whirring sound was coming from your starter. Where are you jumping the terminals? If you jump them at the starter and you have voltage there, the starter will work unless it's bad. The sound was coming from the starter, spinning but not engaging.

Well I took out the starter and we hooked it up to a battery, the starter pushes forward but doesn't spin. I hooked it up in accordance with Jan's instructions (small terminal and big terminal with the braided wire) and the above was the result. After this I am assuming that the problem is the starter now.

is there 12V from the jeep harness little wire in start?

I guess you didn't mean the whirring sound was coming from your starter. Where are you jumping the terminals? If you jump them at the starter and you have voltage there, the starter will work unless it's bad. The sound was coming from the starter, spinning but not engaging. Some starters can be jumped by crossing the big lugs, some cannot. It depends on if the solenoid physically pushes the Bendix out or not. if the starter has a return spring on the bendix, then the solenoid engages the starter. Most Jeep starters, through the '80's and '90's anyways, used a plunger-style solenoid, which pushes the Bendix into gear, so by crossing the two large posts on the solenoid, you are just turning the starter motor, but not engaging the bendix drive, so it won't turn the flywheel. This will make a "whirring" noise. What you need, like already stated, is to try two things. First, use a piece of loose wire to jump the big post on the solenoid that has power from the battery, to the small ignition post on the solenoid. If this cranks the engine, you should then do the next thing.. This would be to have a friend, and a test light or voltage meter, and check if there is 12v on the small ignition wire on the solenoid when the key is turned to the cranking position. If there is no voltage to this wire, then you completely wasted your money on a solenoid and a starter. Sorry. Check your fuses, look into the ignition pin thing.

I don't have a meter but I can borrow one off the ETs at work. Will check the voltage on the small terminal tomorrow. Is there a link to check the plastic ignition thingy?

This is something that I just thought about. My key doesn't lock in the ignition, you can pull the key while it's running. While on the trail it sometimes falls out when I hit a hard bump and it did that night. Could this cause a problem with the plastic thing in the ignition?

Had a mid eighties cutlass that did the Same thing. Never caused a starting problem. Not sure if its the sane for a tj.

Ok I did the jump test but it cranked on the small post and the big post that has the wire from the starter. Not the one that has the battery cable connected. I checked the voltage in the small terminal and got 12 volts right away but it dropped to 11.21 right away. So if I read the posts right this is looking like the ignition thing? How do I fix this?

Another thing I forgot to mention is that when it does crank over the fan moves very slowly.
