1. Dead Battery

The most common reason a car won’t start is a dead battery. If you turn the key and hear clicking or no sound at all, the battery may be dead. To test this, turn on the headlights. If they are dim or don’t turn on at all, the battery is likely the culprit.

To fix a dead battery, you will need to jump-start your car or replace the battery entirely. If you have a jump starter, you can use that to jump your car. Otherwise, you can ask a friend for a jump or call a tow truck. If the battery needs to be replaced, it’s important to purchase the correct size and type of battery for your car.

2. Faulty Starter

If you turn the key and hear a grinding noise, the starter may be the issue. The starter is responsible for cranking the engine, and if it fails, the engine won’t start.

To diagnose a faulty starter, try tapping it gently with a hammer while someone else turns the key. If the engine starts, the starter is likely the problem. However, if tapping the starter doesn’t work, you may need to replace it entirely.

3. Bad Alternator

The alternator is responsible for charging the battery while the engine is running. If the alternator fails, the battery will not be able to hold a charge, and the car may not start.

To test the alternator, start the car and disconnect the negative battery cable while the engine is running. If the engine dies, the alternator is likely the issue. However, if the engine continues to run, the battery may be the problem.

4. Loose or Corroded Battery Connections

If your battery connections are loose or corroded, the battery may not be able to transmit electricity to the starter. To fix this issue, use a wrench to tighten the battery connections. If the connections are corroded, you can use a wire brush to clean them.

5. Bad Ignition Switch

If the engine doesn’t turn over at all, the ignition switch may be the problem. To test this, try turning the key while moving the gear shift lever. If the car starts in neutral but not in park or vice versa, the ignition switch may be to blame.
