What's the reason for the engine not starting?

[MackenzieAnn]

The following are the fault reasons that cause the engine to fail to start: 1. Gasoline flow blockage, characterized by no oil pressure in the engine fuel supply pipe. This situation mostly occurs on particularly cold mornings and is caused by long-term dirt accumulation in the fuel pipeline. When the temperature is extremely low, water and debris mix to block the fuel pipeline, resulting in the inability to start. 2. Poor working condition of the ignition system. In cold weather, due to the 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 and preventing the engine from starting. 3. Valve gumming. In winter, using unclean gasoline can cause the non-combustible gum in the gasoline to accumulate near the intake and exhaust valves and the combustion chamber, making it difficult to start on cold mornings or even preventing ignition.
