* Fuel Pump: The fuel pump is responsible for supplying fuel to the engine. If the fuel pump is faulty or damaged, it can cause the engine to stall or not start at all.
* Fuel Filter: The fuel filter traps dirt and debris from entering the engine. A clogged fuel filter can restrict the flow of fuel to the engine, causing it to run poorly or not start at all.
* Fuel Injectors: The fuel injectors spray fuel into the engine cylinders. If the fuel injectors are clogged or damaged, they can cause the engine to run rich or lean, which can lead to stalling or difficulty starting.
Electrical Issues
* Battery: The battery provides the electrical power needed to start the engine. If the battery is dead or has a low charge, the engine will not start.
* Starter: The starter motor engages the flywheel to turn the engine over. If the starter motor is faulty or damaged, it will not be able to engage the flywheel, preventing the engine from starting.
* Spark Plugs and Wires: The spark plugs provide the spark that ignites the fuel in the engine cylinders. If the spark plugs are worn or damaged, they can cause the engine to misfire or not start. The spark plug wires carry the electrical current from the distributor to the spark plugs. If the spark plug wires are damaged or corroded, they can prevent the spark from reaching the spark plugs, causing the engine to not start.
Mechanical Issues
* Engine Timing: The engine timing refers to the synchronization of the crankshaft and camshaft. If the engine timing is off, it can cause the engine to run poorly or not start at all.
* Engine Compression: The engine compression refers to the pressure of the air and fuel mixture in the engine cylinders. If the engine compression is too low, it can cause the engine to not start or run properly.
* Valvetrain: The valvetrain refers to the components that control the flow of air and fuel into and out of the engine cylinders. If the valvetrain is damaged or worn, it can cause the engine to run poorly or not start at all.
