O2 sensor will not cause no spark conditions, as well as any fuses in the fusebox, or the alternator.
Can you post pics?
Sounds like someone swapped a motor into this Jeep and did a half-assed job.
Make sure there are 3 ground wires hooked to the engine dipstick tube stud.
What is plugged into the ICM/Coil? Not all receptacles are used. there's only one plugged into it.

Okay, may have discovered the problem, well one of them. I check the CPS again and pulled it back out and it's cracked and half. Bits of it were in the hole. I'm frustrated.

I'm not surprised. Both that it's busted to **** and you're frustrated. How on earth did it generate a .6 AC volt signal?

I am half tempted to either run this thing to the junkyard OR get a newer motor and auto tranny to throw in it.
Can you give me an example of how they bust and crank?
