1. Faulty ignition switch:
The ignition switch supplies power to the engine's electrical system. If the switch is faulty, it can momentarily break the circuit and cause the engine to stall.
2. Faulty fuel pump:
The fuel pump delivers gasoline from the fuel tank to the engine. If the pump is failing or has a clogged filter, it can restrict fuel flow and cause the engine to stall.
3. Faulty fuel injector:
Fuel injectors spray gasoline into the engine's cylinders. If an injector is clogged or faulty, it can cause a cylinder to misfire and lead to stalling.
4. Faulty oxygen sensor:
Oxygen sensors measure the amount of oxygen in the exhaust gas and provide feedback to the engine control unit (ECU) to adjust the air-fuel mixture. If an oxygen sensor is faulty, it can provide incorrect information to the ECU, causing the engine to run lean or rich and leading to stalling.
5. Faulty crankshaft position sensor:
The crankshaft position sensor monitors the position of the crankshaft and sends signals to the ECU. If the sensor is faulty, it can send incorrect signals to the ECU, causing the engine to stall.
6. Faulty spark plug wires:
Spark plug wires carry high voltage electricity from the ignition coil to the spark plugs. If the wires are old, cracked, or damaged, they can cause the spark to be weak or intermittent, leading to stalling.
7. Faulty throttle position sensor:
The throttle position sensor measures the position of the throttle valve. If the sensor is faulty, it can provide incorrect information to the ECU, leading to stalling.
It's recommended that you have the vehicle diagnosed by a qualified mechanic to determine the exact cause of the stalling.
