I have battery power at the vcm C4 pin 13 as stated in that topic. My cigerette lighter fuse is good 4x4 fuse is good, I have changed the BCM and the dash gauges and still have the problem.

Currently my security light is on and i have tried doing a rekey but that hasnt helped at all. The security lite stays lit when trying to rekey and wont go off at all. vehicle starts for a second then quits. (hence security feature) Any other ideas on what to try to get this all fixed?
