I just wanted to post this up as a reference for anyone who ever has this issue.
The theft light flashing for 45 seconds means there is a faultly link between the PATS Module and the ECM. In my case I believe the failure was at the Pats module because the car would fire up and shut off within 1 second due to the ECM not receiving the ENABLE signal from the PATS Module.
Normally to repair this you would replace the PATS module and goto a dealership and have them clear out the ID and Pair it to your ECM. I do not like going to dealerships because of the high prices and lack of knowledge. They wanted to charge me $150 for a diagnostic fee when I told them what to do. So I emailed a forum member and had them pull out the entire PATS system from their parts SHO (The year has to match as it's a very picky system with different types). The PATS system is the Module(behind radio), the Transponder(around igntion cylinder), the ignition cylinder and keys and the ECM. It's all very easy to pull and swap. I grabbed the entire system just to be safe but the Transponder probably doesn't have to be swapped unless it is damaged.
Total Cost was only $87 shipped and 20 minutes to install.
I just wanted to let everyone know that a PATS module replacement (transplant) is a possible DIY job without a visit to the dealership.
Hopefully this helps someone in the future!
