$1650 for a new complete engine wire harness?

That sounds irrational

 

Please don't tell me you are throwing parts at it until you get it working.

 

Does it crank?

 

Could just be the starter or the battery fuse.

 

not the battery fuse, we are going to try with a new starter now.

 

Check inertia switch

 

This. I'd be looking pretty hard at finding the specific cause before just spending $1650 to do a whole lot of work that might not even fix the problem.

The price is probably about the norm though.

 

Why not just test the one you have? Should be able to pull it off, put 12vdc on it and see if it works. Then you know if the issue is upstream of the starter.

 

Did you check all the Relays and fuses in the box next to the battery? Are all the ground connections good?
What happens when you try and start the Motor?

 

This thread is fishy

 

Wayyyy to much overkill going on here. None of this makes any sense. First the complete wiring harness and now the starter??? C'mon, who you kidding???

 

OP have you tried putting 12volts straight to the starter?

You know What, I'm out

 

what are you trying to say, this is a joke? come on, if i ddin't had any problem i wouldn't waste my time explaining my situation.

 

The guy is going to spend 1000's of dollars just to find out that it is probably something simple to fix.

 

Ya, ok. Try changing the ignition. If that doesn't work, then the driver's side reading light.

 

I think what everyone is trying to explain to you is that you need a mechanic with better diagnostic skills because he is jumping to really big conclusions that do not seem plausible and he is going to cause you to waste a lot of money. Are you in TJ ? Can you tow the truck up to San Diego to get it better diagnosed ?

 

It sounds like he has a backyard mechanic or a friend helping him out. You can test a starter before trying to install a new one. Anyone can fix a vehicle by replacing parts until it works. The trick is to find the problem without spending a bunch of money on unnecessary parts.

 

We used to start our Jeep with a hammer (wooden handled) across the POS and NEG connection on the starter.. should be pretty easy ... oh and there's a shit ton of cold cranking amps so be careful.

OP did you check the fluid level in your tail lights? Sometimes that causes the issue you described originally.

 

Yup, best way get a bad starter started, jump the selenoid, I used a screw driver
