- Fuel Pump Failure: A faulty fuel pump cannot deliver enough fuel to the engine, causing it to stall.
- Clogged Fuel Filter: A blocked fuel filter restricts fuel flow, leading to engine starvation and stalling.
- Fuel Line Issues: Leaks or blockages in fuel lines can disrupt the fuel supply, causing the engine to die.
2. Electrical Problems:
- Battery Failure: A weak or dead battery cannot provide sufficient electrical power to the engine's ignition system, preventing it from starting or keeping it running.
- Alternator Malfunction: A faulty alternator fails to recharge the battery, leading to gradual power loss and eventual engine stalling.
- Starter Issues: A malfunctioning starter motor can fail to engage the engine's flywheel, preventing it from starting.
3. Ignition System Issues:
- Spark Plug Failure: Worn-out or damaged spark plugs can disrupt the ignition process, causing misfires and engine stalling.
- Ignition Coil Problems: A faulty ignition coil may not generate enough voltage to create a spark, leading to engine failure.
- Distributor Issues: Vehicles with distributor-based ignition systems may experience stalling if the distributor cap, rotor, or ignition wires are faulty.
4. Air-Fuel Mixture Problems:
- Faulty Oxygen Sensor: A malfunctioning oxygen sensor can provide incorrect feedback to the engine's fuel injection system, resulting in an incorrect air-fuel mixture and potential stalling.
- Mass Air Flow Sensor Failure: A faulty MAF sensor can provide incorrect air flow data, leading to an improper air-fuel mixture and engine stalling.
5. Mechanical Problems:
- Engine Timing Issues: Incorrect engine timing can disrupt the proper sequence of combustion, causing the engine to stall.
- Mechanical Component Failures: Internal engine failures, such as piston ring damage or bearing failure, can cause engine stalling.
6. Transmission Issues:
- Transmission Failure: A faulty transmission can prevent power from being transmitted to the wheels, causing the vehicle to stall.
7. Computer Problems:
- Engine Control Unit (ECU) Issues: A malfunctioning ECU can disrupt various engine control functions, leading to stalling.
- Sensor Malfunctions: Faulty sensors (such as crankshaft position sensor or camshaft position sensor) can provide incorrect data to the ECU, causing the engine to stall.
