What are the common causes of a car stalling automatically?

[DiDallas]

Common causes of a car stalling automatically: 1. Triggering the vehicle anti-theft system, which locks the engine, allowing it to start but not run, causing the engine to stall shortly after releasing the key while the anti-theft light remains on; 2. Ignition switch failure, usually caused by poor contact of internal contacts in the ignition switch, often accompanied by dashboard indicators such as the battery light, oil light, and engine warning light not illuminating; 3. Low fuel system pressure, where insufficient fuel is injected during normal injection time, resulting in a mixture that cannot be compressed and ignited. However, during startup, the extended injection time adjusted by the startup program allows enough fuel to be compressed and ignited, enabling the engine to start despite low fuel system pressure.
