I replaced the battery in my 2011 Malibu and now it wont turn over. I was thinking it may be the ignition switch but after some research it may be the ECM? Any ideas?
Have you disarmed the security lock out, it goes active anytime the power is disrupted. Another problem you may have created is if you didn't use the saver tool that plugs into the OBD 2 port you may have lost the factory presets to the body control computer, and that can only be corrected by a GM dealer.
