What should I do if Xiali N3 can t catch fire and doesn t have high voltage?

1. Cause analysis:

Many of the reasons why you can't ignite are caused by improper operation, such as running out of oil, running out of electricity, and having the wrong gear, and these situations are quite common.

1.Out of gas. I went out to rescue a car before, but the fuel gauge showed that it was below the red line, so naturally it could not catch fire.

2.The battery is dead. It may be due to the loss of power caused by the headlights not turned off for a long time or the battery life expires, and it is generally recommended to replace the battery in time after three years.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

3.The gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

Second, what to do and how to solve the reason why the car cannot catch fire.

Reasons for vehicle use: improper oil, no antifreeze, excessive carbon deposit.

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

1. Oil problem. When I was repairing a car, I found that there was water and mud in the fuel tank after dismantling it, and it was impossible to use such oil to keep the car from breaking. Therefore, it is reminded that you must go to a regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the gas gun to filter impurities.

2. No antifreeze added. Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

3. Too much carbon accumulation in the vehicle will also cause the vehicle to not catch fire, and the solution is to reduce the carbon deposit by running at high speed frequently. In addition, there is a small trick for not ignition, before starting the ignition, first screw the key to the ON switch, and then turn it back, and then turn on the strat switch to ignition, let the computer run to calculate the water temperature and the appropriate air intake, and the ignition will be smoother.

First of all, see if there are two small black wires on the negative pole of the battery? That's a computer wire. If the crankshaft position sensor is broken, do not cause no oil and no fire to the computer signal, check the crankshaft position sensor (in the upper right position of the front crankshaft pulley, a very conspicuous place), unplug to see if there is electricity, the plug in and out of the line to measure 2-5V voltage, if there is voltage, then remove the sensor to check, if it is broken, replace.

I just got a three-cylinder Xiali A+ today

No high-pressure fire, no fuel injection signal, the oil pump does not work, and the car does not start. After changing the crankshaft position sensor, it still doesn't hit the car. In the end, it turned out that the two black wires on the negative electrode of the battery were rotten, and the poor contact caused the main computer to have no iron. . .
