Okay, I checked that easy to get to connector and it was not it...of course. So I began looking closer to the linkage and guess what.....I found it. The NSS. YES!
Not only that but the middle wire to the NSS is not connected. Gee, that sounds like victory to me. Okay, looks like I need to rewire or buy a new connector to get this thing back on the road. I'll upload the images of where this part is and my damaged wire for anyone else with this 5.2 V-8 so they can find it easier than me. haha This is on the drivers side.
Here is the connector part at oreillys for the next guy. BWD - Electrical Connector
EDIT: Just called oreillys and they said they can get it there in the next hour. SO, if all goes well, I should have a happy ending to this thread very soon.
The part didn't come in until late so i guess it will be tomorrow before I get it fixed.
I'll report back as soon as I know anything more. I sure appreciate all the helpful posts and interest in helping me along the way. I'll bet you guys can't wait for my next JeepJeep fix adventure. Hint: it is something near the passenger fuse box. lol
I am finally feeling good again about having this problem diagnosed and the part in hand, feeling really good about firing up the Jeepjeep tomorrow...WITH THE KEY!
Replaced the connector. Rewired. Fired right up. For those doing this, the connector package comes with 6 wires. Depending on what gauge you have. Mine was the smaller purple wires. Make sure you have the connector on the wire positioned in the correct up/down position before you push it into the connector snap. If you are not sure, do what i did and look at the existing connector to determine which way is up. I also removed the little yellow keeper piece before I snapped my wires into the connector end. Dont forget to replace the yellow piece if you remove it. Once the 3 wires are snapped in the new connector and the yellow piece is put back, it's just a matter of cutting and splicing the wires back together. I did one at a time to make sure I spliced to correct one's. I used 14-16 wire crimp connectors to mak ethe connection.
Taped it all back up and shoved it back into the plastic tubing. More tape.
Back in business. Thanks for all the help people. Especially this comment, "You've ruled out the NSS when you should not have. " by Jeep Driver.
LOL wow this was awesome. following this thread was like reading a good novel.. I'm here hi fiving the air.. Reason I was reading is I'm having a similar problem with my 97 Jeep. I'm aslo a contractor and just learning all this low voltage circuitry stuff.
Only difference is I have a 5 speed manual. None of the youtubers have a manual demo. seems everyone has that NSS problem. My loads are good, new starter, good batt, good fuses, clean wires..
Can anyone tell me what the manual version of the NSS is called?
I just want to throw in there, that it is not your position crank sensor. It will not start when you hot-wire it, when it is !

I'd specifically like to know a way to test the ignition switch, which is what I am leaning towards being the problem.
My second possibility from what I have read, is the Position Crank Sensor. I have watched a video on how to remove and replace and so, I'd rather not deal with that until I get the ignition switch validated as good, and the ignition tumbler validated as good.
I'd be willing to follow the wire that could be my problem, but inspecting every wire in the harness all over the Jeep seems like a wild goose chase, no offense. I know these Jeeps used poor quality wiring plus put wires in exposed areas where they shouldn't be.
But since I am waiting on responses, I will go out and see what I can see about your suggestion. Thanks for the response. I'll report back any findings.

Thanks a lot. I try to keep it light and entertaining. Stay tuned for Chapter 2 lol coming soon I'm sure.
I suggest you go to a online auto parts store and look up the NSS for your vehicle transmission type etc. That's what got me headed in the right direction, once I knew what the part looked like. Did your reverse light check fail? See if you have reverse lights in reverse. That is a pretty good indicator that points to NSS not knowing what gear you are in. May be totally different for a manual transmission. There was a mention of a ParkNeutral switch but haynes manual suggested this part be serviced by a pro only. Hope you get it figured out.
Yes. It will not crank in neutral. I have read all about that Neutral Safety Switch on here though. That's how I knew to check that. I tried shifting it all around and it does nothing in park and neutral and wiggling around.
Remember though that it will crank up and start in Park by arcing the solenoid. So to me, that rules out NSS.
Tomorrow after work I'll take a knife to that bundled up wire package and inspect thoroughly although I do not want to. lol
Yes an automatic transmission.
Isn't this incorrect? Maybe I'm wrong but I thought with a bad NSS it will start by jumping starter. That's what I thought would rule in a bad NSS if it does start that way.

My NSS had a wire that was corroded off. The middle wire. But i was able to jump start with arcing the solenoid even with bad wire. So arcing and starting success does not rule out the NSS as being the problem. It can be arc started with a non functioning NSS.
That confused me but Jeep Driver set me straight on that.
