[KayleeLee]

Reasons for diesel engine failing to start: 1. No fuel in the tank or forgetting to open the fuel tank switch. 2. Air or excessive moisture in the fuel supply system. 3. Blockage in the pipeline or filter. 4. Wear of the injection pump plunger. 5. Sticking of the injection pump delivery valve or breakage of the delivery valve spring. 6. Breakage of the injection pump plunger spring, resulting in no pressure in the injection pump. 7. Sticking of the injection pump plunger in the plunger sleeve, etc. More details are as follows: 1. The advantages of a diesel engine include high torque and good economic performance. Each working cycle of a diesel engine also goes through four strokes: intake, compression, power, and exhaust. 2. However, since the fuel used in diesel engines is diesel, which has higher viscosity than gasoline and is less volatile, and its auto-ignition temperature is lower than gasoline, the formation of the combustible mixture and the ignition method are different from those of gasoline engines.
