- Ignition System Issues: Problems with the ignition switch, ignition coil, or spark plugs can prevent the engine from firing.
- Fuel System Problems: A clogged fuel filter, a faulty fuel pump, or a malfunctioning fuel injector can prevent fuel from reaching the engine.
- Security System Malfunction: Sometimes, the car’s anti-theft system can prevent the engine from starting if it detects a problem.
- Dead Key Fob Battery: If you have a keyless ignition system, a dead key fob battery could prevent the car from recognizing the key and starting. how to change the battery in cadillac key fob provides instructions for various Cadillac models.
