Hello and welcome to JustAnswerCustomer
Do you have a voltmeter to do some electrical testing?
i do have a volt meter it just seems like the starter doesnt engage
ok well let me say this first when i jump the starter it has power to it because it will wind but wont turn the motor over and when i turn the key i just get a click could it be a bad ground?
It could be many different things at this point. We need to start by running through these tests I mentioned and that will tell us where to go from there. There is an issue that is starting to become the common problem with no-starts on these, but I'd like to do these tests to make sure what is happening.
I'll be at work for the first half of tomorrow, but I do get to check in here periodically. If you reply back to me I'll get back to you as quick as I can. After that I'll be online from about the middle of the afternoon for the rest of the day and then all day Sunday.
Did you check both the large positive cable at the starter, and piercing the small solenoid wire while someone held the key to crank>
If you do have good battery voltage at the positive cable and on the solenoid wire that leaves two things. You've either got a bad starter or poor connection at the solenoid wire terminal. If you've seen the starter work ok consistently when powered up out of the Jeep then it should be the terminal.
What happens on these is the female blade terminal on the solenoid wire will corrode. It will corrode where it makes contact with the terminal on the solenoid, but it will also corrode between the terminal and the wire at the crimp. This will cause a no crank situation. You can cut the old terminal off, make sure the wire is clean and then put a new terminal on the wire, or you could replace that section of the wiring harness, which also comes with the battery cables.
Yes, the solenoid wire is the small wire at the starter. This corrosion isn't somewhere you could clean. It is going to be inside the female part of the terminal on the wire, and/or at the crimp where this terminal attaches to the harness. This isn't something that you will be able to clean, the terminal will have to be cut off, the wire verified to be corrosion free, and a new terminal installed.
Excellent, I'm glad to hear you got it fixed!
