What are the reasons for a China V diesel vehicle failing to start?

[VonRicardo]

Here are the reasons why a China V diesel vehicle may fail to start: 1. Low ambient temperature: In cold weather, the diesel engine should be preheated properly, otherwise it may be difficult to start. 2. Air or excessive moisture in the fuel supply system: The symptom is that the starting speed is not low but the engine does not ignite, and white smoke comes out of the exhaust pipe. The inspection method is to loosen the vent screw on the diesel filter or the high-pressure fuel pipe on the high-pressure pump. If air comes out, it indicates the presence of air. The solution is to tighten all fuel line connections, then loosen the vent screw on the high-pressure pump and turn the crankshaft to remove the air. If water is found in the diesel, it can be removed in the same way. If there is too much water in the diesel, the diesel needs to be replaced. 3. Blockage in the pipeline or filter: The solution is to use an air pump to clear the pipeline, clean the filter, and check whether the fuel tank filler screen is intact.
