- Fuel pump inertia switch: The fuel pump inertia switch is a safety feature that cuts off the fuel supply to the engine in the event of a collision. It can be tripped by a sudden jolt, such as hitting a bump, and may need to be reset by pressing a button or switch near the fuel pump or engine compartment.
- Fuel pump relay: The fuel pump relay is an electrical switch that controls the power supply to the fuel pump. It can be damaged by a power surge or other electrical fault, and may need to be replaced.
- Fuel filter: The fuel filter is a device that removes impurities from the fuel supply. If the fuel filter is clogged, it can restrict the flow of fuel to the engine and cause it to stall.
- Fuel injector: The fuel injectors are responsible for spraying fuel into the engine cylinders. A faulty fuel injector can cause the engine to misfire or stall.
- Ignition switch: The ignition switch supplies power to the engine's ignition system. A faulty ignition switch can prevent the engine from starting.
- Starter solenoid: The starter solenoid engages the starter motor to start the engine. A faulty starter solenoid can prevent the starter motor from engaging, or may not let it disengage leaving starter still cranking on engine while it is running
- Battery: If the battery is not providing enough voltage to the engine, it may not start or may run poorly.
