So after days of research and trying different things to fix the issue I narrowed it down to the fuel pressure regulator in the actual sending unit. What happened was the FPR metal housing had broke loose from the plastic housing on the return line. The fuel was bypassing the FPR and it caused the pressure to drop dramatically. In testing the part it completely broke away from the FPR housing and obviously needed to be replaced. After finding a used sending unit on ebay I replaced the part and the car started up and ran even better than before since it now had a new fuel filter, clean throttle body, IAC, and TPS. I hope this will help someone that might have the same problem as I did.
