Started it up and starter wouldn't disengage. Turned the jeep off now won't start wont even try to crank. Gauges still work lights windows etc. disconnected pos batt term and reconnected now nothing no dash lights int lights windows etc. but fogs and cb wired direct to battery work. Very odd just went to lunch with my wife not 30 min before and no issues.

 

Most likely your battery. Have it tested at Autozone or another parts store.

 

Tow truck on its way to take to jeep.

I have been having a rough idle issue in the last couple weeks. And the new drivers side head has been ticking again the last couple thousand miles.
Something just now reset and now I have lights and windows etc. again but still no start.

 

Just got my 12 sahara back after 2 weeks @ dealer for no power, was a short under dash they opened connecter soldered splice & recrimped connecter works now. this was a intermitten isssue also had trouble with alarm not disengaging with fob or key. let dealership figure it out,

 

Luckily it was just the starter that fried. Got it back yesterday. Figured that's what it was since it got stuck in the on position.
