What's the reason for suddenly failing to start the engine?

[LeEvelyn]

The reasons for suddenly failing to start the engine are as follows: 1. Insufficient rotation speed: The starter begins to rotate but lacks sufficient power, eventually making only clicking sounds without turning. Low temperatures in winter and forgetting to turn off certain electrical devices can prevent the vehicle from starting, especially after prolonged short-distance, low-speed usage in winter, which causes the battery voltage to drop below the rated value, making starting and normal operation impossible. Emergency solution: If this occurs, please call the service station for assistance, seek a jump-start from another vehicle, or temporarily start the engine, after which the battery must be recharged at the service station. 2. No oil pressure: There is no oil pressure in the engine's fuel supply line. This situation often occurs on particularly cold mornings due to long-term contamination of the fuel lines. At extremely low temperatures, water mixed with debris can block the fuel lines, resulting in failure to start. Emergency solution: Place the vehicle in a warm environment, and it should start after a while; alternatively, thoroughly clean the fuel lines as a permanent solution.
