In order to help the truck driver friends who are out of the house, I have now made a simple combing of the problems that the vehicles that I usually encounter are difficult to start. I hope that I can inspire everyone and solve the difficulties encountered in the road.

First, the oil side

1, the fuel tank is not oil, this is the simplest and most overlooked problem, then the situation is to add diesel.

2, the air into the oil system, a simple way to exhaust air.

3, oil pipeline, filter plugging, it can only be based on the oil road, vines, check, disassembly and cleaning, after this situation is resolved, to remind truck drivers, the original filter.

4, the injector is damaged, the atomization is bad, replace the injector; the oil pump problem, the oil pump pressure is low, or the fuel can not be sprayed, replace the oil pump. These two situations will also be encountered, but the probability is relatively small. Generally, attention should be paid to the quality of diesel fuel. Do not use cheap diesel oil because of greediness, so that the oil nozzle and oil pump are damaged, which is not worth the loss.

Second, the circuit aspect

1. If the battery voltage is too low, the engine will not reach the minimum starting speed. In this case, only the battery is recharged; or the battery case is bulged, the battery function is disabled, and no power is stored. In this case, the battery is replaced.

2. Start relay failure and replace starter relay. This kind of situation occurs in the old car. When the relay is used for a long time, the contact of the contact is not good, and there will be a phenomenon that sometimes it can be hit and sometimes it cannot be played.

3, the electrical line connector is off, directly wired and secure, or the fuse next to the battery is not in good contact, unplug and reinstall. Before this failure, the truck driver encountered a similar fault, causing sweating, and finally found that only the fuse on the starting line was loose.

4. If the starter is damaged, the starter gear cannot be embedded in the flywheel ring gear, check and repair or replace the starter.

5, the sensor is damaged, check the corresponding fault code, and replace the corresponding sensor. If you encounter multiple hits to catch a fire, consider whether the sensor is damaged, such as a camshaft or crankshaft position sensor.

6, do not take a taxi in the neutral state, certainly can not be hit, to adjust the gear to the neutral; or the neutral switch is damaged, step on the clutch to catch the fire. I hope that when the card friend encounters the fire again, he will first step on the clutch to see if he can drive the car. If it can catch fire normally, consider the neutral switch is damaged.

7. When the temperature is low in winter, the engine has a preheating function, and it can only catch fire after the preheating is completed.

Basically from the oil circuit and circuit, we have included our common failures that can't be fired. There are also several uncommon situations. This kind of fault will occur in old cars, for example:

1, the piston ring and the cylinder liner are seriously worn and the helium is severe;

2, piston ring breakage is serious;

3, the valve leaks, check the valve and valve seat sealing, and re-adjust the valve clearance.

After the seal from the oil circuit, the circuit and the engine.

After summing up these three aspects, I believe that when you encounter your own car and can’t catch fire, or when it’s difficult to catch fire, it’s not so fearful or anxious. Some simple questions can be checked and judged. Here, remind the truck driver that if you encounter problems, don't worry. First of all, from easy to difficult, from simple to complex, even if you can't really solve it, there is a versatile way to call the manufacturer service hotline. At the same time, see if your car has passed the warranty period. If the warranty period is really over, it is probably a matter of spending more money, and will not let yourself be helpless. I sincerely hope that the above summary will help the truck drivers running around the country day and night!
