What are the reasons for the car stalling immediately after starting?
1 Answers
Reasons for the car stalling immediately after starting: 1. Carbon deposits: During cold starts, the engine temperature is low, and fuel is difficult to evaporate or vaporize. If there is severe carbon buildup in the fuel lines or intake manifold, it can lead to an overly lean air-fuel mixture entering the combustion chamber, resulting in unstable idling or stalling immediately after ignition. 2. Fuel and air issues: A faulty fuel pump may suddenly jam or malfunction, causing the fuel pump to underperform or stop, leading to insufficient fuel supply and stalling. 3. Low fuel system pressure: Insufficient fuel supply due to low fuel pump pressure, fuel line leaks, low electrical current, or a damaged fuel pressure regulator. 4. Clogged or leaking fuel injectors, causing poor atomization and insufficient fuel supply, leading to stalling. Precautions for starting the car: 1. Avoid prolonged continuous use of the starter. 2. Avoid restarting the engine within less than 15 seconds and releasing the key immediately after starting the engine. 3. Avoid pressing the accelerator pedal too hard immediately after starting. 4. Avoid driving off immediately when the idle is unstable. 5. Avoid sudden starts without observing the surroundings. 6. For automatic transmission vehicles, avoid push-starting or towing to start, as it may damage the transmission.
