Had my fuse box replaced after my interior lights stopped working. My stereo stopped working, dome lights, gauges, horn was going off on its own. My right kick panel fuse box was replaced after it was found to be wet and corroded. However the main issue was that my jeep would try to start while the key was out and it was in park. Once the fusebox was replaced, all the things I listed worked properly except that when the key was in the on position , in neutral or park, my jeep would start and continue trying to start, and when it started it would keep cranking. I replaced my started recently so I don't want to ruin it. I'm thinking it could be the ignition switch, but I don't have an official wiring diagram for the starter circuit to diagnose it. Any help or input would be greatly appreciated because I want to fix it myself, it gets expensive as some would know. Thanks

 

Might want to look at the ignition switch assembly.

 

That's what I was thinking, I don't know what to look at though , I don't want to start taking things apart before I know what I'm looking at. Or should I just replace it and see if it fixes it..

 

Go back to the original issue, the wet fuse block. If you have a leak someplace you'll be chasing problems to no end. Pulling the fuses, a hair drier and a finger nail file could have fixed that. You have to find the source of the moisture before you go any further..
But your mileage may vary..

 

^^^ try this first...
The ignition switch on your year is a one piece unit, not really all that rebuildable. But , J/P magazine did an article dealing with this back in Oct of 012ish good info worth looking at.

 

There is a relay in the PDC that sends power to the starter solenoid. Your ignition key provides +12V to that relay when you turn it to 'start', the NSS provides ground to that relay in Park or Neutral. That's basically all there is to that circuit. Either the ignition switch is failing (likely- it's a known weak point) or you have a wiring short somewhere. Or someone installed a remote starter and it's now losing it's mind. (it happens!)

 

Sounds a bit the opposite of what ususally comes along, the " won't start"....yours keeps frantically starting...even without key...spooky.
Will keep an eye on this thread to see what comes out of this...
