Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
Does the check engine light come on for bulb check when first turning key to on position? Is vehicle starting now?
CHeck to see if pink wire going to ignition module has power with key in start position, if not check to see if 20 amp ECM1 fuse is blown. If fuse is good but no voltage then replace the ignition switch. Let me know how it goes or if you have more questions, thanks.
