I have a 05 Liberty factory diesel that will not start. Changed the ignition switch & module. Nothing. With key in the on position I could jump it at the starter relay and solenoid. But now it won't start by jumping it. Took it to a 5 Star jeep dealership. 6 weeks later they "tapped out". The tried a new starter, relays, ignition switch / module, key and receiver and various other things. They did they had about 60 hours in it. Of course I had them remove everything they put on that didn't fix it. Wasn't going to fix it by process of elimination.... Any thoughts? Someone once said something about a relay that would stop it from starting but I forget the name. Something like Auto Shut Down?
