How to deal with truck trailer cannot start?

First of all, from the aspect of oil system .

1,The tank is out of gas. The simplest but potentially overlooked problem is that if this is the case, diesel oil must be added.

2,In the oil system, air is introduced into the system, and air is simply discharged. Especially in CIMC trucks trailer , many drivers have a filter element installed in addition, the use of a long time will appear in the pipeline seal is not strict phenomenon, clearly see the filter element transparent filter cup or transparent tubing bubble flow phenomenon, this phenomenon is the oil into the air.

3,Oil pipeline, filter plug, that can only be according to the direction of the oil road, along the vine touch melon, investigation, disassembly and cleaning, in this case, to remind drivers friends, with the original filter, and not more than 30,000 kilometers to replace diesel filter.

4,Injector damage, poor atomization, replace the injector; oil pump problems, low pump pressure, or can not inject oil, replace the pump. These two situations will also encounter, but the probability is relatively small, we should generally pay attention to the quality of diesel oil, not because of greed for small and cheap, the use of inferior diesel oil, so that the nozzle, pump damage, not worth the loss.

Second ,circuit system.

1,If the battery voltage is too low for the engine to reach the minimum starting speed, the battery can only be recharged in this case; or if the battery enclosure is bulged, the battery fails to function and no electricity is stored, the battery can be replaced in this case.

2,Start relay failure, replace starter relay. This kind of situation appears in the old car quite many, after the relay uses the time long contact is not good, may appear sometimes can start but cannot start.

3,Electrical wiring connectors fall off, direct wiring and firm, or battery fuse contact is not good, pull out and reinstall.

4,Starter is damaged, starter gear can not be embedded in flywheel gear ring, check and repair or replace starter.

5,Sensor damage, check the corresponding fault code, and replace the corresponding sensor. If you encounter multiple failures, consider whether the sensor is damaged, such as camshaft or crankshaft position sensor damage.

6,If you don't start in neutral gear, you can't start. Set the gear to neutral gear, or if the neutral switch is damaged, press the clutch to catch fire.

7,When the temperature is low in winter, the engine has preheating function, and it can be activated after the preheating is finished.
