1. Oil supply system failure
1) Parking solenoid inlet valve failure. The solution is shown in the section of common failures of the front supply system.
2)The amount of diesel fuel in the tank is very low or the tank suction valve is not open. According to the instructions to fill the diesel fuel, open the fuel tank suction valve.
3)Fuel supply line or diesel filter clogging. Clean the oil supply line and pipe joint screen, discharge the diesel fuel filter bottom water or replace the diesel fuel filter.
4)There is air in the oil supply system. Unscrew the bleeder screw on the diesel fuel filter, press the hand crank arm of the pump to repeatedly pump several times to exhaust, and then tighten the bleeder screw, and check whether the oil pipe joints are screwed tight.
5)The oil pump does not supply oil. The solution to see the front supply system common faults section.
6)Injector pump failure. The solution is shown in the section of common faults of the front supply system.
7) Injector injection or bite. The solution is still in the front supply system common faults section.
8) injection advance angle is not allowed. This time should be adjusted according to the specified data after tightening the injection pump. Engine cylinder air leakage causes and solutions
