A dead battery is the most common reason why a car won't turn over. When the battery is dead, it doesn't have enough power to crank the engine. You can check if your battery is dead by looking at the battery indicator light on your dashboard. If the light is on, that means your battery is low and needs to be charged.
2. Bad starter
The starter is responsible for cranking the engine. If the starter is bad, it won't be able to turn the engine over. You can check if your starter is bad by listening for a clicking sound when you turn the key in the ignition. If you hear a clicking sound, that means your starter is trying to engage, but it's not able to turn the engine over.
3. Bad ignition switch
The ignition switch is responsible for sending power to the starter. If the ignition switch is bad, it won't be able to send power to the starter, and the engine won't turn over. You can check if your ignition switch is bad by trying to start your car in different positions. If the car starts in one position but not another, that means your ignition switch is bad.
4. Bad ignition wiring
The ignition wiring is responsible for carrying power from the battery to the starter. If the ignition wiring is bad, it won't be able to carry power to the starter, and the engine won't turn over. You can check if your ignition wiring is bad by looking for any loose or damaged wires.
5. Bad flywheel**
The flywheel is a heavy metal disc that stores energy from the starter and releases it back to the engine, helping it to start and keep running smoothly. However, if the flywheel is damaged or cracked, it won't be able to perform its function correctly, leading to starting problems.
These are just a few of the reasons why a car won't turn over. If you're having trouble starting your car, it's important to take it to a mechanic to have it diagnosed.
