What are the reasons for stalling when starting from a stop?
1 Answers
The reasons for stalling when starting from a stop are as follows: 1. Fuel system: During normal operation, the fuel pump draws fuel from the tank, which passes through the filter into the distribution lines and is then injected by the fuel injectors to form an air-fuel mixture. In this process, the fuel pump and injectors are most prone to failure, followed by filter and fuel line blockages. The solution is to clean the fuel system. To reduce such occurrences, always refuel at reputable gas stations with the correct gasoline grade and maintain adequate fuel levels, avoiding letting the fuel drop below the red line. 2. Throttle valve blockage: The throttle valve is undoubtedly the most critical component and also the most susceptible to issues. The solution is to clean the throttle valve. 3. Abnormal spark plug ignition: Replace spark plugs according to their service life. In gasoline engines, the combustible mixture is ignited by the spark plug when compression nears top dead center. Therefore, when spark plugs fail to function, it can cause the vehicle to stall. The solution is to replace the spark plugs or clean the electrodes and adjust the central electrode length. Additionally, insufficient battery voltage, leakage, ignition coil failure, or wiring issues can all lead to poor ignition or stalling.
