Car Not Starting, Check Engine Light On
When your car won’t start and the check engine light is on, it can be a frustrating and confusing experience. Here’s a comprehensive guide that will help you diagnose and fix the problem.
1. Check the battery
A dead or weak battery is the most common reason why a car won’t start. Start by checking the battery terminals for corrosion or loose connections. If the terminals are clean and tight, try jump-starting the car to see if that solves the problem. If the car still won’t start, you may need to replace the battery.
2. Check the starter motor
The starter motor is responsible for turning over the engine. If the starter motor is not working, the car will not start. Try tapping the starter motor with a hammer or wrench to see if that gets it working. If tapping the starter motor does not solve the problem, you may need to replace it.
3. Check the fuel system
A problem with the fuel system can also prevent the car from starting. Check the fuel filter for clogs and replace it if necessary. Also, check for any fuel leaks and repair them as needed. If you suspect that there is a problem with the fuel pump, you can try to prime the fuel system by turning the key to the “on” position without starting the car. You should hear the fuel pump humming for a few seconds. If you don’t hear the fuel pump humming, it may need to be replaced.
4. Check the spark plugs
The spark plugs are responsible for igniting the fuel in the engine. If the spark plugs are worn or fouled, they can prevent the car from starting. Remove the spark plugs and check them for wear or damage. If the spark plugs are worn or damaged, you will need to replace them.
5. Check the ignition coils
The ignition coils are responsible for providing the spark plugs with the power they need to ignite the fuel. If the ignition coils are not working, the car will not start. Check the ignition coils for any cracks or damage. If the ignition coils are cracked or damaged, you will need to replace them.
6. Check the electrical system
A problem with the electrical system can also prevent the car from starting. Check the battery cables for any corrosion or loose connections. Also, check the alternator for any signs of damage. If the alternator is damaged, it will need to be replaced.
7. Have the car diagnosed by a mechanic
If you have checked all of the above items and the car still won’t start, you may need to have the car diagnosed by a mechanic. A mechanic will be able to use specialized tools to diagnose the problem and recommend the best course of action.
Conclusion
If your car won’t start and the check engine light is on, it can be a frustrating and confusing experience. However, by following the steps outlined in this guide, you should be able to diagnose and fix the problem. If you are not comfortable working on your car, you can always have it diagnosed by a mechanic.
