QUESTION: Bought a 2003 Ford Explorer with a Code Alarm system in it. The car battery died, put a new battery in, and still, the car won't start. Just makes 1 click noise but no crank no nothing...?
ANSWER: If it's clicked at the starter motor then it's not the Code Alarm module causing the problem. The system can only completely stop all power from reaching the starter motor, you wouldn't even hear a click at the starter if it was the Code Alarms built-in kill-switch. Sounds like you may have additional problems like a bad or corroded ground wire or a bad starter motor. But, always press the unlock/disarm button on the Code Alarm remote before you try to start the vehicle.
