What are the reasons for a car starting and then automatically stalling?

[BrookeLee]

The main reasons for a car starting and then automatically stalling are the following 4 points: 1. Triggering the car's anti-theft system: If the car's anti-theft system is triggered, the engine can start but cannot operate normally, leading to the vehicle stalling after starting. 2. Faulty ignition switch: If the car's ignition switch malfunctions, the car may experience issues such as stalling after starting and the vehicle fault warning light turning on. 3. Severe carbon buildup in the car engine: If the engine has severe carbon buildup, fuel cannot burn effectively in the cylinders, resulting in the vehicle stalling after starting. 4. Low fuel system pressure: If the car's fuel system pressure is low, the fuel will not burn effectively.
