(1) in non-oil tank or forget to switch the fuel tank opening.
(2) the fuel supply system in the air or water too much. Starting phenomenon not low speed but not on fire, smoke and exhaust pipes run. Diesel filter method is the screw or deflated on the high pressure pump high-pressure pipeline screw loose, if air out that the air. The method is to exclude the Joint Oil tightening, and then high pressure will be put on the gas pump screw fastening loose, rotating crankshaft, excluding air. Diesel found in water, can also be ruled out the same way. If too much water in diesel, to the replacement of diesel.
(3) pipe or filter plugging. Processing method is used to pump-pipe blowing, cleaning filter, and check the filter tank refueling mouth intact.
(4) fuel pump plunger wear, should be replaced at this time plunger.
(5) fuel pump oil from the oil valve jammed or broken valve spring. High-pressure tubing joints can be unloaded, will be filling out the valve seat and valve cleaning, filling valve spring break required replacement.
(6) fuel pump plunger spring break, causing no pressure injection pump.
(7) fuel pump plunger stuck in the Inner plunger. When Circuit normal, shaking fixed crankshaft, piston, the piston and piston sets jammed. Should open the fuel pump plunger and the plunger and cleaning kits.
(8) injector needle stuck. Injector should be dismantled and removed from the nozzle needle, cleaning, or replacement of the valve counterpart.
(9) injection time is not correct, in accordance with the regulations re-injection calibration time.
