2000 C5 issues starting and running
Hello, I just recently got a 2000 C5 and for a few days it had been running fine, but the other day, I tried to start it and the gauges wouldn't cycle and the car would turn over like normal but would not start, so did some research trying to find out whats going on with the car and read that it could be the security system, made a resistor bypass on the ignition thinking it was the chip in the key having a bad connection or something, don't know we tried a lot of things, sometimes the car starts up and runs fine, other times the key won't even make the gauges cycle or turn the car over, sometimes it does, sometimes it cycles starts and then just dies moments later, and we got a list of codes and here they are!

Yes we have a code list, and thanks, I made sure ours was the same and it is, we did reset the codes and it made a few go away, the bottom 8 codes are for both doors and there seems to be a slight power drain when the doors open and we're trying to see if that's causing any issues (fixing code list)
