What are the reasons for a car stalling automatically after starting?

[LaElle]

Reasons for a car stalling automatically after starting: 1. Severe carbon buildup in the engine: When there is severe carbon buildup in the car engine and fuel cannot burn effectively in the cylinders, the vehicle may stall after starting; 2. Activation of the car's anti-theft system: If the car's anti-theft system is triggered, the engine may start but fail to operate normally, leading to the vehicle stalling automatically after starting; 3. Ignition switch failure: If the car's ignition switch malfunctions, the vehicle may stall automatically after starting, and the malfunction indicator light may turn on. This situation is more complex and requires inspection and repair by professionals at an auto repair shop or 4S store; 4. Low fuel system pressure: If the car's fuel system pressure is low, fuel will not burn effectively, necessitating an inspection of the fuel system.
