I bought a brand new battery. I turned my camaro on after the brake job to test drive it and it started. it seemed like it made kind of a funny sound when it started but it could just be in my head. anyways the speedometer started to fluctuate at idle and the RPM's remained the same. I noticed i had the head lights unplugged since i replaced the fender and bumper. so i turned the car off and plugged in the headlights. i started the car and now it wont start it just clicks. its a brand new battery and i tested the voltage and it was fine. i got the starter removed and test it and it fine. but im wondering if a fuse was blown because all the wires going through the grommet in doors is hooked to nothing. power window wires and the speaker. its because i changed the door and im gonna put my old manual window regulator in it. could it be that some of these wires that are hooked to nothing be touching metal and linked in with the head lights and blowing a fuse not causing it to start? if not what else could it be?
