If you hold the key over, and jiggle the shifter in park or neutral and it starts, it's your NSS. http://bc4x4.com/tech/2010/jeep-neut...ty-switch-nss/
There's a diagram in my sig showing the bottom right ground wire on your start relay. If jiggling doesn't work try grounding that. (Make sure it's in park!)

Not sure what you mean when you say try gounding it.
At this point if i take the wire that goes from the starter solenoid to the starter relay off of the relay and go direct to the pos terminal of the battery it starts. Oh and the key has to be in the on position. So im happy it starts. Not completely dead in the water.
Is there an easier way to jump the starter? (if thats what im doing. not sure of the terminology.)

Not sure about an 88 but 97-01 would definitely unplug the nss and jump the 2 terminals. Do a search on jumping nss and pics will come up

Here's the relay>
"Grounding" means connect the black bottom right to any metal or the negative battery terminal. Bumper to bumper, pretty much all the metal on the Jeep should be grounded to the Neg battery post.
The point being, it's the job of the NSS to only ground that while you are in park or neutral. If grounding that makes it work, you need to change out or clean the NSS. (see the earlier link on cleaning it.) You don't want to leave it jumped and have someone accidentally run over someone's kid, or pet. That would be pretty stupid!

Just tried it still no start. Am i crazy for thinking that it might be easier to install a push button start?

I started driving it regularly. I just put the key in, pop the hood, touch green cable to battery and BOOOM. My beast starts. At this point im going to have a mechanic look at it. Hopefully he can diagnose it and if its cheap and easy Ill do it if not....... Push button start it is. It seems pretty easy if I can make the connection that i make under the hood (green to red) Under my dash it shouldnt be a problem. Any body have any tips if i go this route?

I'd see if my ignition switch is putting power to the ign. terminal on the relay. I gather it's adjustable, IE, the switch can be moved up or down a little so that when you turn the key, the rod down from the tumbler activates 'Start" (not sure if it pulls or pushes).
The connector on the ign switch is a known weak point...

Hey, an 88? Maybe the current from your new switch is not making it through the C-101 connector. I'd check for juice from the key at the relay, and/or check Cruiser's tips on cleaning or eliminating the C-101 connector.

I think your right on. I went to clean the c101 and found it fried. I hoping this my problem. I am planning on by passing the c101 and splicing the wires on friday. Ill keep you updated.

Update: I bypassed the C101 connector last Friday. As I inspected it closer I realized that it wasnt fried. All the terminals were just covered in black gunk. So I had a feeling I wasnt going to get the results I wanted. From what I gather this c101 is problem spot anyway so im glad i got rid of it. It was quite a process but got thru with it.
This is how it turned out. Pretty happy with it.
After all the time Ive spent working on this thing Ive decided to go with the quick fix and install a push button start. I put it where the lighter socket was. Looks awsome. I plan on adding some extra 12v sockets to make up for eliminating it. Ill post pics as soon as I can.

Heres some pics of the process still have to get some of the push button.
C101 connection
You can see the black gunk from this angle.
Was not looking forward to splicing all those wires.
A little heat and Im almost done
Half way thru.....
Soldered every wire together one at a time. As i went along I realized how important this was. The wires on the left side were faded and discolored way more than the right so the colors didnt match on most. Youcan kinda see it here.
