- Fuel delivery issues: A lack of fuel can cause a vehicle to shut off without stalling or sputtering. Check the fuel filter, fuel pump, and fuel lines for any clogs or leaks. Make sure the fuel tank has enough fuel.
- Electrical problems: Faulty ignition switches, bad wiring, or loose connections can cause a vehicle to shut off while driving. Check the battery, starter, alternator, and distributor for any problems.
- Engine cooling problems: Overheating can cause a vehicle to shut off. Check the coolant level, thermostat, and water pump for any issues.
- Sensor problems: Faulty sensors can provide incorrect information to the engine computer, which can cause the engine to shut off. Check the oxygen sensor, mass airflow sensor, and throttle position sensor for any problems.
- Computer problems: A malfunctioning engine control computer (ECM) can cause a vehicle to shut off. Check the ECM for any loose connections or damage.
