Hi fellas, I have an 09 ss that I can't get running. It ran mint with no codes up than I parked it in my shop and pulled the battery out of it for my other car. I just put the battery back in two months later and went to start it - when you turn the key ahead the fuel pump runs constant, no fuel on the gauge , service eps , no xm radio and the car won't crank. I pulled all the fuses , ran a scan tool on it (no codes) and crawled underneath it and crossed the terminals on the starter to see if I had power to it and nothing. Could my bcm or ECM be fried? Anyone have any ideas?
