DAILY DRIVER need to get to work but no clue what went wrong.
New battery new starter New fuses 4.0L
I spent ALL day trying too figure this weird problem out. No clue..

Heres what went down.
I bought a NEW radio. Along with some new relay fuses due too fuel pump going out out of wack from other fuse. Replaced and Fixed. BUT
Soon as i Put my new radio in. and drove home something was smoking behind it. so i pulled it all out ASAP. and new fuse relays in..

My jeep WILL NOT DO ANYTHING.
No power at all accept my windows and lights.
Gauges dont work fuel pump dont work nothing cranks.
not even my alarm works.
Sooo i did the screw driver trick to crank my jeep to see if it was the starter.
Nope. Jeep would crank with the ignition turned on but no power to anything.No fuel..
Next i thought it would be the NSS. Nope wiggled jiggled nothing..
Next i tired doing the CSP by unplugging it to see if the offset with the guages would at least work..
Nope..
Battery cables are in check. Negitive is fine positive is coming back good.
ONLY thing i didnt check was ignition switch in the collum and the starter Relay BUT that dont explain the NO Power when key is ON. ?

Someone pleaseeee please help. Jeeep well taken care of. Would the radio cables cause the jeep to shut down??

There is a fusible link somewhere... I'm not familiar with your specific year, but they are often near the starter relay, tied to the main battery cable.

I think the next thing on your list should be to check your ignition switch. Whacky things happen that that guy cooks it's brains. They're often melted when ya pull them off the column. It's mounted to the column under the dash, follow the actuator rod coming from the ignition key cylinder.

first thing id do is unplug radio then check fuses with test light for power on both sides with key in run position....

PROBLEM FOUND!
Thanks for the help. i re-Traced the lines in the radio followed it around abit tore down the WHOLE dash. nothing followed my heater...
LONE BEHOLD.. my heater was still on with key off. turned it off..my jeep started RIGHT up.

weird. turned the heater on. Died on me. Traced the wires the "line" for the High and low cable was ripped apart touching metal... shorting it everytime.

THANKS everyone! now i can get to work in my JEEP
