The process to figuring out what was the exact problem was extensive and also very mysterious. There was no starter ground coming from the PCM to the pulse module and no positive feed from the pulse module to the start itself. After replacing the pulse module there still wasn't any ground coming from the PCM and that was also replaced. New keys were ordered and the PCM, pulse, SKREEM were all communicating with no problems. (These parts were replaced individually once and then a second time to be programmed all at once).

The problem was my "original key", lock cylinders and door locking module were not matching/cut per my VIN. The new keys they ordered off my VIN would not turn the ignition in the car. They would open my glove box but, wouldn't start the car or manually open the doors. My old key would do the exact opposite but, now the SKREEM, PCM and pulse were programmed to the new keys.

They had to take the metal blade from my old key and put it in the electronics of the new key to get the car to start. Basically they believe at one point the key, ignition cylinder, door locking module and possible the PCM, SKREEM were all from a donor crossfire.

I've had this car when it only had 400 miles on it but, I bet ill never figure out if it was stolen beforehand or had these parts replaced before I bought it. Since I've never had any problems with the key, ignition cylinder or door locking module I'm positive it wasn't tampered with during ownership.

The bill I won't disclose is massive due to it being at the dealer but, at this point I needed the car back!
