Well now the Jeep wont start again.
It's not the starter, not the NSS, not a bad battery (tested with a jump).
What can it be?
I get no crank, no click, no difference in P or N or any other gear. Voltage is good, it looks solid over 12 volts in the car.
Ignition switch? What else?

Also if there is no clicking try turning off your alarm, It happened to me just turn key to start and push button in for 4 sec. That is if it has alarm.

try jumping the terminals on the starter itself. i bet you it will start.
try this, hold your key in the start position (all the way forward to start), then wiggle the shifter forward and backward in neutral slowly tho, you should hear it click. find that spot again and i'm sure it will start.
do all this with the ignition held forward all the way, until it starts that is.
but jumping the terminals is a sure fire way, if not, replace starter.

I cleaned out some relays in the engine bay, and then she fired up! Drove for over an hour, turned off, fires right back up!
Suspecting the starter relay or similar...
Tried to jump starter but had no one to keep in the start position...

you don't need anyone to hold the key in the start position when you jump the starter. you only need the key in the run position.
but glad you got it going, hope it was just as simple as the starter relay.

As a summary:
Clean tighten terminals.
New battery.
New starter.
New NSS.
New relays.
Can you outline exactly which relays you swapped out?
Also, what write up did you use to change the NSS?

Same thing happens to my jeep all the time. Did anyone ever replace the battery cable ends? If mine does that I just leave the door open with the key in the ignition and wiggle the ground cable wire until I hear the buzzer going then I know I'm good. All I need to do is fix that connection but not until the packer game is over lol

New starter, check.
New NSS, check.
New relays, no. I haven't replaced any relays yet, only cleaned them.
I used the bc4x4 write up to change the NSS.

Also sprayed down the starter relay behind the battery.
Not sure it classifies as cleaning but it helped last night!
That's the write-up I used!

I have a similar problem that I have been fighting with for about a month now and I have narrowed it down to the NSS (even though I was sure that it wasn't the NSS). The problem was so intermittent that I could never properly troubleshoot it. I tested the NSS wire right at the relay several times over the past few weeks and tested properly even when it wouldn't start.
This Sunday it finally decided to no longer be intermittent and would no start at all. Got out the multimeter and every wire on the relay tested as it should except the NSS. The reading on the NSS wire was all over the place. Ran a jumper wire from ground to the NSS wire on the relay (just as a test, I don't plan on leaving it grounded) starts every time now.
I am still not convinced that it is the actual NSS itself and here are the reasons:
1. I have had the NSS fail before and the check engine light came on and logged code right away. Its not doing that this time.
2. During the times that it would not start, throwing a chargers on it or simply waiting would allow it to start (never touching the shifter).
3. About a year ago when the NSS started acting up I pulled it apart and cleaned it, lightly sanded all the contacts and put it back together and adjusted. It was in very good condition, just dirty and worked perfectly for months before the starting issue popped up.
If it was the NSS not showing the correct position P,N, etc, simply throwing a charger on it would not solve the problem. I also have intermittent door lock problems. I have a feeling that there is a either a ground or bulkhead connector that is loose or has some corrosion on it. Shortly after I first got the Jeep I had intermittent problems with the guages so I pulled them out and the connector wasn't pushed together all the way. At that time it only had 77,000 and had been owned by a couple that towed it behind there motorhome so I am pretty sure no one had been in there before.
In theory, if the problem is a connection, I could spen $385 on a new NSS and it would not solve the problem. My next test when I have time is to test with wire right at the NSS switch and if it tests OK then it will be a very difficult process to track down the problem. I have checked all of the visible connectors and grounds.
Sorry for the long post, I figured I would share my similar experience. For now I have a jumper wire attached to the relay. Once I check the NSS switch itself I will post what I find.

I've just replaced both the starter and NSS. Ordered a new Starter Relay to see what that'll do...
Wish I had your tenacious detective skills, i have soon replaced all parts so it should work fine soon!
Keep it up!
