Bad ECM
2005 MN6 24,500 mi. Car would not start. It was not DBS. Opened the door, window indexed, dash lights came on, pushed the button – NATA and the dash went blank. Tried wiggling the wheel, P-break, clutch, left the car & came back several times. Still no joy.
Had it towed to the dealer using the GM Roadside Assistance that’s part of the warrantee.
Diagnostic revealed an internal open on circuit 625 thereby disabling the crank relay. They replaced and reprogrammed the ECM.
Towed by Chevy & fixed under warrantee.
