No Crank, No Start After Clearing Check Engine / Security Codes?
2002 BUICK REGAL GS Supercharged: Solid Security light and solid Check Engine Light lit for over a year with the engine running fine before scanning. I scanned all systems with Blue Driver OBD2 Diagnostic Scan Tool while the engine was running. Scan revealed confirmed codes P0102 and B2958. It also displayed historical Security codes B2960, B2957 and B2961. I selected "Clear All Codes" and then the engine died. I attempted to restart the vehicle but the vehicle only clicked, no crank, no start. I attempted the GM Passlock relearn procedure but it did not work. No crank, no start and the solid Security light, Check Engine light still remain. I scanned the system again and current Security code B2958 and historical Security code B2960 are the only codes that remain. Battery is fully charged. Can a scan tool really cause a vehicle not to start? How do I fix this?
Read through this link. Good info and a way to bypass http://www.diy-gm-security.com/
SOLVED: I removed the radio/HVAC bezel and steering column top/bottom covers to gain access to the ignition cylinder. One of the small white wires on the ignition switch that sends the resistance value from the key pellet to the GM Passkey system was broken. Before fixing anything, I attempted to start the car and it started right up with wire broken and the security light lit. I soldered the wire together. Car now starts and runs fine with no Security light and no current security codes. I'm still not sure what the cause of the original no start issue was. It truly seemed like the engine dying and not restarting correlated with clearing the security codes. Obviously the wire damage was a long standing issue that needed to be corrected. Anyways, thank you for your input. It is truly appreciated.
