That wire over there is unplugged.

You don't really expect a diagnosis based on this, do you?
You're going to have to give a LOT more info than this.
What is/isn't it doing? Turning over? Sparking? Getting any power? Getting fuel? What wiring harness was replaced, and with what type? How's the battery? Who rebuilt the engine? Who installed it? What king of fuel system? What kind of ignition system?
These are a few of the basics. Maybe someone can help from there once there is some actual info included.

Thanks Kruzin. You're right. Not my finest. Anyway, here we go... Motor was done at Bate's engines in Centerville, TN. They did the heads, and the shortblock. I reassembled from there. New clutch, oil pump, and water pump. Nothing jumped up, all oe replacement. I wrestled it back in with a little trouble, but not too bad. Set #1 to TDC on the compression stroke. Lined up new distributor with new points and condenser (this was set up by my mechanic to get this thing running back before I decided to rebuild the motor, so I'm assuming they are gapped correctly) and checked and rechecked firing order(18436572). Installed new plugs. Replaced entire factory wiring harness. The poor thing had been set on fire a couple times by the looks of it. Installed Painless 22 circuit, customizable cj harness. There are some circuits I'm not using, but they are terminated and coiled away. Again, nothing added. No accesory lights, winch, cb, or news radio. New Battery is sending power to new coil. Getting spark. Turning over. Has coughed and sputtered but won't stay running. Carburetor was rebuilt by myself last summer (not much confidence there) but I should be able to at least get the thing started? I'm a novice wrench at best. I'm trying to learn as I go. I think this is one of the coolest things I've ever done! I'm hooked man.

Sounds like the distributor is 180 out.

180 out?

I'm 99.9% positive I have the dist. set at TDC on #1 compression stroke. I used a compression gauge to monitor the stroke as I turned the motor over. as soon as it came up, I barred the motor over manually to the TDC mark on the timing cover. I used a McDonalds straw to make sure I was at the top of the stroke.

It only takes 3 things to make a motor run, compression, spark and fuel. You say you have compression and spark so that only leaves fuel. Try slowly dribbling some fuel down the carb throat as someone cranks the motor over.
