1. Check the fuel pressure regulator. If the regulator is defective, fuel will leak from the fuel line, causing the vehicle to stall.
2. Check the fuel filter. A clogged fuel filter can restrict the flow of fuel, causing the vehicle not to start.
3. Check the fuel pump. A defective fuel pump will not be able to provide adequate fuel pressure to start the engine.
4. Check the fuel injectors and make sure they are not damaged. If they are, the fuel will not be introduced properly into the cylinders.
Ignition System:
1. Check the spark plugs. Make sure they are clean and properly gapped.
2. Check the spark plug wires. Make sure they are not damaged and are properly connected.
3. Check the distributor cap. Make sure it is clean and free of corrosion.
4. Check the ignition coil. If it is damaged, the spark plugs will not receive enough power to create a spark.
Battery:
1. Check the battery voltage. If the battery voltage is too low, the vehicle will not start.
2. Check the battery cables. If the cables are damaged or loose, the vehicle may not start.
3. Check the battery terminals. If the terminals are dirty or corroded, the vehicle may not start.
