What Are the Reasons for a Car Starting and Then Stalling?

[StCody]

Car starting and then stalling can be attributed to the following reasons: 1. Severe carbon buildup in the car's engine can prevent effective fuel combustion in the cylinders, leading to the vehicle stalling after starting. In such cases, it is necessary to promptly clean the engine's carbon deposits. 2. If the car's anti-theft system is triggered, the engine may start but fail to operate normally, resulting in the vehicle automatically stalling after starting. This situation commonly occurs after replacing the car key or its battery, so it is essential to recode the key after such replacements. 3. A faulty ignition switch can cause the car to stall after starting and trigger the vehicle's malfunction warning light. This issue is more complex and requires inspection and repair by professionals at an auto repair shop or 4S store. 4. Low pressure in the car's fuel system can prevent effective fuel combustion, leading to stalling after starting. In this scenario, the fuel system needs to be inspected.
