Xiali car does not need to open the key for a long time, the oil pump does not pump the oil, what is

Vehicles that have been stopped for a long time will gradually deteriorate the technical condition of each assembly and mechanism due to atmospheric erosion, resulting in the loss of original technical performance. To mitigate this adverse effect, the owner should always carry out the necessary maintenance work on the stopped vehicle to keep it in good performance condition.

1. Prevent the aging and deterioration of rubber products.

Rubber products on automobiles, such as tires, transmission belts and dust covers, often age, swell or shape, resulting in deterioration of performance and shortened service life.

Like the aging of rubber products, it is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon, which is easy to absorb oxygen in the air and oxidize, and vulcanized rubber also has a certain air permeability, and oxygen is easy to enter the interior to oxidize. In particular, direct sunlight can promote the rapid aging of rubber. When rubber products are stained with gasoline and engine oil, it will cause the volume to expand, the gum to become loose, and the elasticity to decrease.

Automobile repair and maintenance net.

In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.

2. Prevent metal rusting.

Rust is mainly caused by the combined action of moisture, oxygen and corrosive substances in the air. Therefore, for cars that have been parked for a long time, the metal surface should be kept clean. The garage where the vehicle is parked should be ventilated frequently so that the relative humidity of the air is kept below 70%.

Dust, dirt and moisture need to be removed from the car in a timely manner. The parts that are easy to rust and the surface of the parts should be coated with oil, grease or wrapped with oiled paper. The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior.

3. Prevent mildew and carpet of cotton and linen products.

It absorbs moisture easily. Especially in humid areas and rainy seasons, it is more susceptible to damp mildew. Therefore, the owner should check the cotton and linen products on the car frequently, dry them in a timely manner, and keep them dry.

4. Prevent the anti-knock performance of gasoline from decreasing.

The anti-knock performance of gasoline is determined by the octane number of gasoline. When the car is stopped for a long time, the octane number of gasoline decreases with the loss of light components and the increase of gum content, so that its anti-knock resistance is reduced. Therefore, the gasoline tank should be tightly closed and the temperature should not be too high.

It is best not to store gasoline for too long.

5. Check the working condition of the engine frequently.

Start the engine at least once a month, idle for 4-5min, and check the operation of the engine. If there is any abnormal phenomenon, it needs to be adjusted and repaired in time.

Also, check the battery frequently. The electrolyte level of the battery must be 10-15mm higher than the plate, and distilled water should be added in time when it is insufficient, and the power should be kept sufficient, and the battery should be charged if necessary. "

Hello, it may be useless for a long time, the oil pump is stuck inside and does not work, this situation can only be solved by replacing the oil pump, I am very happy to solve your problem, I hope to help you, I wish you a happy car!

Hello, this should be the oil pump stuck, generally you try to use something to gently knock on the bottom of the fuel tank, to see if you can activate the oil pump (this is the soil method), if not, can only disassemble and inspect, now the oil pump is generally replaced by the assembly, can not be repaired on a better oil pump assembly, and it is recommended that you should start the vehicle regularly, otherwise, tires, batteries, oil pumps, etc. will be affected, I hope to help you, I wish you a happy car!

If the key oil pump does not produce oil, it is recommended to use a wooden stick to knock on the top of the fuel tank. See if the oil pump can work properly. If it works properly, you need to check the plug of the oil pump or the oil pump itself for problems.

If the oil still does not come out, check the wiring or relay of the oil pump, there is a problem. Happy with your car. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello friends, I haven't opened it for a long time, and I need to warm it up before turning it on.

Hello. The oil pump does not work for the following reasons.

The fuse of the first oil pump is damaged.

The relay of the second oil pump is damaged and does not engage.

Third, the oil pump itself was damaged.

Fourth, the wiring harness of the oil pump is squeezed and broken and does not work.

I hope it can help you, and I wish you a happy car! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Brother, you gave too little information to judge! The gasoline pump does not work, nothing more than the DAO is due to the following reasons: Inside.

1. The pump is broken.

2. The circuit of the gasoline pump is not open, just check whether there is electricity on the pump.

3. Replace the gasoline filter and the oil suction port in the fuel tank to see if it is blocked.

4. Clean the oil circuit.

Find a roadside shop, half a day is enough to get it done.

You can peel off the oil.

The shell of the BAI pump relay allows the owner to du

Turn on the ignition switch in the car to see if the relay is engaged1If the suction of the oil pump is not right, you can use the test light to see if the oil pump interface has electricity. If there is electricity, the oil pump will be changed, and if there is no power, the relay will fly the wire to the oil pump for testing.

2.If it does not engage, the voltage from the computer to the relay must be measured (because the questioner did not indicate what brand the computer is, so the definition of the computer pins cannot be given here, and the Xiali computer is directly below the center console).

If you need further tips, you can ask questions.

Summary. Hello, happy to answer your questions.

Xiali N5 oil pump has just been replaced, and it often does not catch fire, what is the reason?

Hello, happy to answer your questions.

What is the blame for this question in general.

What's going on?

Hello, flush hall oil pump OK, check the following places, 1The oil pump relay is damaged, 2The hydraulic control valve is stuck, and Kaixiao 3There is a problem with the plug of the computer or the computer of the teller, and the 4 crankshaft sensor is not working well.

If there is a problem with the crankshaft sensor, there should be a fault code.

No, if there is a problem with the crankshaft signal, the code will not be reported.

I don't seem to have a crankshaft sensor for my Xiali displacement.

2014 ex-factory Xiali displacement.

Without distributor, with crankshaft sensor.

There are oil pump relays, but I don't know what distributor you're talking about.

Then there must be a crankshaft sensor, check it out.

The driving habits are different, the road conditions are different, the traffic jam, the load, the oil, the hot and cold air, whether the run-in period of the old car is different, the fuel consumption is not the same, the general comprehensive fuel consumption is about 8-10.

How many oils means how many liters of oil per 100 kilometers. is a colloquial idiom. Vehicle fuel consumption is generally calculated based on fuel consumption per 100 kilometers, such as 10L fuel consumption per 100 kilometers, which means that the vehicle needs 10L gasoline for 100 kilometers.

It is recommended to calculate it yourself according to the following method:

1.According to the trip computer on the car. Generally, better cars have a trip computer with real-time fuel consumption and average fuel consumption.

When you want to calculate fuel consumption, empty the data inside, and the average fuel consumption read is more accurate. Some cars do not support the driving computer or the computer does not support clearing data, so the second method can only be used.

Some people also say that the data calculated by the driving computer is inaccurate. But the amount of fuel is controlled by the car, and the car can also know the number of kilometers, so why is the data inaccurate? So I think the data calculated by the driving computer should still be reliable.

2.Each of the following steps is required to be strictly implemented, otherwise the calculated fuel consumption may not be accurate. When refueling first, add until you jump the gun, don't refuel at this time, and record the kilometers at this time.

Why is this method more accurate to calculate fuel consumption, because the size of the fuel tank of the car is fixed, and the fuel gun is also standard, so when it is added to the jump gun, basically the amount of fuel in the fuel tank is fixed, so we can use this method to ensure the accuracy of fuel consumption calculation to the greatest extent.

Of course, now gas stations always find excuses to refuel more for business purposes, such as to make a whole amount of money (strongly bs here either), so it is difficult to implement this method.

If it's broken, buy a new one and replace it.
