Check Engine Light On and Car Won’t Start
What does it mean when the check engine light is on and the car won’t start?
When the check engine light is on, it means that the engine control module (ECM) has detected a problem with the engine. The ECM is a computer that controls the engine’s operation, and it uses sensors to monitor the engine’s performance. When a sensor detects a problem, the ECM will turn on the check engine light to alert the driver.
If the check engine light is on and the car won’t start, it could be a sign of a serious problem. The problem could be with the engine itself, or it could be with one of the engine’s components, such as the fuel system, the ignition system, or the electrical system.
What should I do if the check engine light is on and the car won’t start?
If the check engine light is on and the car won’t start, the first thing you should do is try to restart the car. If the car still won’t start, you should have it towed to a mechanic.
The mechanic will be able to diagnose the problem and repair it. The cost of the repair will depend on the severity of the problem.
What are some of the common causes of the check engine light being on and the car not starting?
Some of the common causes of the check engine light being on and the car not starting include:
- A problem with the fuel system, such as a clogged fuel filter or a faulty fuel pump
- A problem with the ignition system, such as a bad spark plug or a faulty ignition coil
- A problem with the electrical system, such as a dead battery or a faulty alternator
- A problem with the engine itself, such as a blown head gasket or a seized piston
How can I prevent the check engine light from coming on and the car from not starting?
There are a few things you can do to prevent the check engine light from coming on and the car from not starting, including:
- Regularly maintain your car, including changing the oil and filter, and checking the tires and brakes
- Use high-quality fuel
- Avoid driving in harsh conditions, such as in extreme heat or cold
