What Causes the Engine to Stall Immediately After Starting?

[BrookeRose]

The reasons for the engine stalling immediately after starting: 1. The vehicle's anti-theft system is triggered, locking the engine so that it can start but not run. Releasing the key causes the engine to sputter once or twice before stalling, accompanied by the anti-theft light illuminating; 2. Faulty ignition switch, where the ignition line has power during startup but loses power and stalls when the key is released. This is due to poor contact of internal contacts in the ignition switch, often accompanied by the dashboard battery light, oil light, and engine fault light not illuminating; 3. Damaged ignition module or a faulty ignition reference signal line from the ignition module to the engine computer; 4. Insufficient air intake, such as a leaking intake pipe or a blocked exhaust pipe.
