1. Check the battery. Make sure that the battery is properly connected and has sufficient charge. If the battery is weak or dead, it may not be able to provide enough power to start the car.
2. Check the starter solenoid. The starter solenoid is responsible for engaging the starter motor. If the solenoid is faulty, it won't be able to send power to the starter motor and the car won't start.
3. Check the ignition switch. The ignition switch is responsible for sending power to the starter solenoid. If the ignition switch is faulty, it won't be able to send power to the solenoid and the car won't start.
4. Check the wiring. Check all of the wiring connections between the battery, starter solenoid, ignition switch, and starter motor. Make sure that the wires are properly connected and that there are no loose or frayed wires.
If you're not comfortable performing these checks on your own, you can take your car to a mechanic for diagnosis and repair.
