Reasons for the Car Stalling Immediately After Starting?

[Florence]

Reasons for the car stalling immediately after starting are as follows: 1. Carbon deposits. Cold starts cause the engine temperature to be low, making fuel difficult to vaporize. Severe carbon buildup in the fuel lines, intake passages, and other areas can lead to excessively lean air-fuel mixture entering the cylinders for combustion, resulting in unstable idling, immediate stalling after ignition, and other phenomena. 2. Fuel and air issues. Insufficient fuel supply due to low fuel system pressure, fuel line leaks, small supply current, or a damaged fuel pressure regulator; clogged or leaking fuel injectors causing poor atomization, leading to insufficient fuel supply and stalling. 3. Ignition problems. Issues such as faulty ignition coils, spark plug wires, or spark plugs can cause insufficient ignition energy, leading to stalling. 4. Power supply issues. Faults in the starter motor or battery can make it difficult or even impossible to start the engine.
