Why does a car suddenly fail to start?
1 Answers
The reasons why a car suddenly fails to start are: 1. Battery depletion: The characteristic manifestation is that the starter begins to turn but the rotation speed is insufficient, and later the starter only makes a clicking sound without turning. Low temperatures in winter and forgetting to turn off certain electrical equipment can cause the vehicle to fail to start; 2. Gasoline flow obstruction: The characteristic manifestation is that there is no oil pressure in the engine fuel supply pipe. This situation often occurs on cold mornings and is caused by long-term dirt accumulation in the fuel pipeline; 3. Poor working condition of the ignition system: The characteristic manifestation is that in cold weather, due to low intake air temperature, the fuel does not atomize well in the cylinder. If combined with insufficient ignition energy, the result will be cylinder flooding, where excessive fuel accumulates in the cylinder, exceeding the ignition limit concentration.
