Your friend was suggesting you bypass everything to see if it'll start.

If you're not comfortable doing this then don't... I don't want you to get run over.

Turn the key to the run position.

PUT THE JEEP IN PARK and set the parking brake.

Climb under the Jeep with a screw driver and short the small post to the big post with the positive wire that's headed to the battery.

Short the two posts that the orange lines point to in this picture.

If it starts then your NSS, starter relay or fuse is bad. Basically that narrows it down to one circuit instead of the entire ignition system and other issues. I'd bet on the NSS.

PLEASE DON'T RUN YOURSELF OVER



You can also hold the key in the start position and jiggle the shifter and neutral.

After that I checked to see if the engine was seized by turning it manually.

After that I hooked up the bottom line of the orange lines indicated in your photo back up. I hooked the jumper cables up to the battery and to the starter so that the positive was to the location of your top orange line and the negative to the body of the starter and turned ignition to see if it would spin. It did not.

Does it acomplish the samething without teh possibility of getting run over? I am willing to try it if need be.

Not exactly. You have to supply power to the small post to make the starter spin. Just touch a screw driver to both the posts that the orange wires are pointing to with the key ON and tell us what happens. Hold it there till the Jeep starts. Then go shift from Park to 1st with the Jeep off about 50 times then try to start it in neutral.

You didn't answer my question at the very beginning of my post. What's EXACTLY is it doing when you turn the key?
