- Starter motor faulty. The starter motor is responsible for converting electrical energy from the battery into mechanical energy to turn the engine over. If the starter motor is faulty, it may not be able to draw enough power from the battery to turn the engine over.
- Bad ignition switch. Bad ignition switch could also be a cause since it connects battery to the starter solenoid.
- Bad solenoid. The solenoid is a switch that engages the starter motor. If the solenoid is bad, it may not be able to send power to the starter motor.
- Loose or corroded battery connections. Loose or corroded battery connections can prevent the battery from providing power to the starter motor.
- Faulty spark plugs or wires. Faulty spark plugs or wires can prevent the engine from firing, even if the starter motor is working properly.
- A faulty fuel pump or fuel filter will prevent fuel from reaching the engine, which will also prevent it from starting.
- A failed ignition coil will prevent the spark plugs from firing, which will also prevent the engine from starting.
