Engine Stalls Immediately After Starting?
2 Answers
The reasons for the engine stalling immediately after starting are: 1. Short circuit or power failure in the engine or car computer; 2. Unclear fuel path; 3. Excessive carbon buildup in the throttle body leading to insufficient throttle opening; 4. Clogged fuel injector resulting in low fuel injection; 5. Low oil pressure from the fuel pump; 6. Use of substandard fuel. The engine is the device that provides power to the car, determining its power, economy, stability, and environmental friendliness. Its working principle is: converting the chemical energy of fuel into the mechanical energy of piston movement to output power externally. Engines are categorized into: 1. Diesel engines; 2. Gasoline engines; 3. Electric vehicle motors; 4. Hybrid motors.
I encountered the same issue with my car before - it would stall immediately after a cold start. After hours of troubleshooting, it turned out to be a faulty fuel pump. Actually, there are several common causes for this: excessive carbon buildup in the throttle body causing it to stick, worn-out spark plugs with weak ignition, or a malfunctioning crankshaft position sensor leading to ECU misjudgment. I've personally experienced intake system leaks too, where the MAF sensor gave inaccurate readings resulting in an overly lean air-fuel mixture that caused instant stalling. My advice is to prioritize checking the fuel system and ignition system, especially for older vehicles - pay extra attention to whether the fuel pressure is normal. If you're not familiar with electrical circuits, it's best not to disassemble components yourself. Just take it to a repair shop to read the trouble codes - that's the most straightforward solution, since repeated starting attempts can really wear out the starter motor.
