Diesel engine can not start, how to rule out?

The reasons for this failure are many, users can exclude from the following aspects:

● Open the fuel tank to check if the fuel quantity is insufficient, if not, give fuel;
● Check whether the fuel tank switch is open and the air hole is blocked. If yes, open the switch and clear the air hole of the fuel tank.
● Overhaul the pipeline seal of the fuel system and eliminate air;
● Check whether the tubing is blocked or broken. If yes, unscrew the tubing, replace the damaged parts, and tighten the tubing connector;
● Check the sealing of valves, piston rings and cylinder liners, cylinder gaskets, etc., and give them repairs;
● Check the starter circuit, electromagnetic switch, armature and magnetic field coils, shafts and bearings;
● Check the fuel pump's oil valve, plunger pay, and spring, adjust the adjustment lever. At the same time, clean the fuel injector, grind the needle valve, adjust the injection pressure or replace the nozzle;
