- Check the battery and battery cables. Make sure the battery is properly charged and the cables are clean and free of corrosion.

- Check the fuel filter. A clogged fuel filter can restrict fuel flow and cause the engine to stall.

- Check the air filter. A dirty air filter can restrict air flow and cause the engine to stall.

- Check the throttle body. A dirty throttle body can cause the engine to stall.

- Check the idle air control valve (IAC valve). A faulty IAC valve can cause the engine to stall.

- Check the fuel pressure. Low fuel pressure can cause the engine to stall.

- Check the ignition switch. A faulty ignition switch can cause the engine to stall.
