I know this is not a Cadillac problem but I posted this on Chevy forum with no response. I have a 2008 Chevy Equinox 3.4 v6. I changed plugs and wires and when I went to start it the key was locked in and no power. Got key out,connected battery cables for 30 seconds, but still no power.The only electrical connection disconnected was wiring harness to coils. Would you happen to know or find out what I need to wake it up!! Thanks.
