My jeep has acted crazy since I got it. It mainly was the NSS with me having to put it in neutral to start it now I have to jump the relay or crawl under it with a screwdriver and jump it. Now it spins over and will not start unless you give it throttle while spinning but after it starts if you let off the throttle it dies. I do have a engine light that recently just popped up.
This is just a start of the ****aroos with my jeep. Thanks in advance for any help y'all supply

Start with rebuilding the NSS. Here's a very detailed link with lots of pictures.

Then go to an auto parts store and pull the code. Sounds like it might be a fuel delivery problem with how it only dies when you let off the throttle. I'd suspect the fuel pump

Get the codes. They are invaluable in resolving any issues. Anything less is guess work.

The symptoms of having to tip in the throttle to start it can be caused by a faulty "throttle position sensor", but there are certainly are other possibilities.

That's where the CODES come in.
