Car Turns On But Not Engine
Possible Causes
1. Dead battery
A dead battery is the most common reason why a car will turn on but not start. The battery provides the electrical power needed to start the engine, and if it is dead, the starter motor will not be able to turn the engine over. You can check if the battery is dead by using a voltmeter to measure the voltage across the terminals. If the voltage is below 12 volts, the battery is dead and will need to be replaced.
2. Faulty starter motor
The starter motor is responsible for turning the engine over. If the starter motor is faulty, it will not be able to turn the engine over, even if the battery is good. You can check if the starter motor is faulty by listening for a clicking sound when you turn the key to the “start” position. If you hear a clicking sound, it means that the starter motor is not engaging with the flywheel.
3. Bad ignition switch
The ignition switch is responsible for sending power to the starter motor. If the ignition switch is bad, it will not be able to send power to the starter motor, and the engine will not start. You can check if the ignition switch is bad by using a multimeter to test for continuity between the terminals. If there is no continuity, the ignition switch is bad and will need to be replaced.
4. Faulty fuel system
The fuel system is responsible for delivering fuel to the engine. If the fuel system is faulty, the engine will not be able to get the fuel it needs to run. You can check if the fuel system is faulty by checking the fuel pressure. If the fuel pressure is low, it means that the fuel system is not delivering enough fuel to the engine.
5. Faulty spark plugs
The spark plugs are responsible for igniting the fuel in the engine. If the spark plugs are faulty, they will not be able to ignite the fuel, and the engine will not start. You can check if the spark plugs are faulty by removing them from the engine and inspecting them. If the spark plugs are worn or damaged, they will need to be replaced.
How to Fix It
If your car turns on but not engine, the first thing you should do is check the battery. If the battery is dead, you will need to replace it. If the battery is good, you can then check the starter motor, ignition switch, fuel system, and spark plugs. Once you have found the cause of the problem, you can then fix it.
Conclusion
If your car turns on but not engine, it can be a frustrating experience. However, by following the steps outlined in this guide, you can troubleshoot the problem and get your car running again in no time.
