Has anybody else with a 2006 on up style Impala had a condition where after the battery was removed and replaced the key was stuck in the ignition, the interior lights do not work, no power to the moonroof and the car fails to start? We just did a water pump on my buddies 2006 LTZ and removed the battery to gain easier access. With the new water pump back in place, battery leads connected to a fully charged battery we tried starting the car and nothing. My friend said this happened twice before and he was able to get the car going after removed the RAP fuse and negative battery lead over night. Tried this and nothing. The only things working are the speedometer, bell chimes and radio. Does this sound like a bad ignition switch or a faulty BCM perhaps?
