Was this car stolen or in an accident? Lets clear all codes and then turn the main system on without starting the engine, then run the codes again and let me know what they are, it sounds like you may have a bad PCM which can cause all of these codes. Also I would check all fuses, here is a guide to help and the fuse locations as well.
