FAW and diesel EFI sometimes can t be refueled

1.The spark plug loses its ability to ignite.

2.The throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

3.Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

4.The load operation of the transmission will destroy the quality and friction characteristics of the transmission oil, increase the friction and wear, and the transmission noise will follow, and at the same time, the sludge (impurities or dirt) will also be generated inside the transmission (such as the valve body), resulting in the transmission stuttering, disgearing, impact, skidding, stalling, abnormal noise, delay, high temperature, oil leakage, etc. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

It's normal, this happens when starting or changing gears uphill!

1. What is the reason why the EFI diesel truck cannot be refueled? 1. The fuel metering function of the vehicle is damaged, which will lead to the failure to add oil, which is generally caused by the serious wear of the internal plunger of the fuel metering unit of the vehicle. 2. The damage inside the fuel injector will cause the incorrect amount of fuel injection and oil return, resulting in insufficient power of the vehicle, so that the oil cannot be added, and sometimes the diesel pump will be damaged and the oil will not be added.

3. If the connection between the line and the plug connector is not correct, there will also be the phenomenon of not adding oil, just like the plug of a fuel injector in the engine is loosened, and a cylinder will not start to work, and when the line connection of the car fuel injector is not good, it will also lead to the vehicle not being able to add oil. 4. When the diesel filter of the vehicle is blocked or particularly dirty, it will cause insufficient oil supply to the parts in the vehicle and cause it to fail to ignite.

Second, how to solve it.

1. When the fuel metering function of the car is damaged, you can go to the repair shop to find a repair worker for repair or replacement, so as to solve the problem of not adding oil. 2. When the inside of the fuel injector is damaged, it can also be repaired or replaced. 3. When it is found that the line connection between the line and the connector is not normal, the line can be repaired.

4. The diesel filter of the vehicle can be cleaned regularly, and the diesel filter can be cleaned and then installed.

Hello, glad to answer for you It takes some time to type, so please wait.

It should be disassembled and overhauled, if the air release pipe does not flow or the oil flow is not smooth, the resistance is not large when pumping oil with the hand oil pump, the oil inlet pipe of the fine filter can be removed, and the oil flow in the oil pipe of the fine filter is not smooth, at this time, the oil pump inlet pipe is loosened to see if there is oil flow, if it is explained that the oil pump inlet and outlet valves are not closed strictly, it should be ground and repaired, if the air release pipe is not smooth, and the handle resistance is large when pumping oil, you can remove the filter oil inlet pipe joint, and the handle resistance is not large when pumping oil, And the unimpeded flow of diesel from the oil pipe indicates that the filter is blocked, and it should be removed for inspection and repair.

Any more questions? You can also pay attention to the answer, if you have any questions in the future, you can consult directly, if you are satisfied with my reply, please give me a thumbs up after the end of the click.

The reasons why the diesel engine oil pump does not inject fuel are as follows: 1. If the problem of single-cylinder engine is easier to solve, check whether the oil circuit is smooth and whether there is air in the oil channel, and it is best to remove the oil pipe input into the oil pump for inspection; 2. Then install the oil pump in the state of oil discharge, and finally check the oil pump, pull down the decompression, increase the throttle, try a few more times, and remove the oil pump if it still doesn't work; 3. Check whether the plunger sleeve is stuck, if not, try again, or if it doesn't work, it may be that the oil pump is stuck, then replace it. Jiang Hanlin [Certified Expert] Jiang Hanlin is a certified car master, with many years of industry work experience + ask him if the diesel engine injector does not inject fuel, for the following reasons Traditional diesel engine:

1. There is air resistance in the oil pipeline (the filter is not filled with diesel fuel or there is a leak in the pipeline when the filter is replaced) 2. The diesel pump core is seriously worn or broken High-pressure common rail diesel engine: 1. The low-pressure oil pump or high-pressure oil pump is faulty 2. The ECU does not receive the signal from the crankshaft position sensor 3.

Summary. 2. The EFI diesel engine cannot ignite, because the EFI system of the vehicle is faulty, in this case, the fuel cannot be injected into the cylinder. In this case, it may be caused by the poor connection of the low-voltage circuit or the leakage of the high-voltage line, which will affect the car and make it impossible to drive.

3. It is because the starter of the vehicle is damaged, so that the vehicle cannot start normally. In this case, the only way to do this is to find a car repair shop or a 4S shop for repair or replacement. If it is not dealt with in time, it will also have a certain impact on the car.

The EFI diesel car can't work, the engine is out of gas, and the full fuel can't catch fire.

Hello, I am the main teacher of Q&A, and I have helped 5000+ people solve all problems satisfactorily! Your question I have received, please give me a few minutes to write the answer, I am not a robot, please do not end the order, thank you pro! I am your exclusive technician, attentive and attentive, dedicated to your car or solve vehicle problems, to find solutions and methods for you.

Hello friends. Dear, what is the reason why the EFI diesel engine does not catch fire? 1. The EFI diesel engine cannot catch fire because the vehicle is in a low temperature area.

Remember to make sure you distinguish whether the fire is not ignited, whether it is a cold car or a hot car. If the cold car does not ignite, the solution is very simple, you need to fire multiple times, so that the cylinder block in the vehicle is preheated.

2. The EFI diesel engine cannot ignite, because the EFI system of the vehicle is faulty, in this case, the fuel cannot be injected into the cylinder. In this case, it may be caused by the poor connection of the low-voltage circuit or the leakage of the high-voltage line, which will affect the car and make it impossible to drive. 3. It is because the starter of the vehicle is damaged, so that the vehicle cannot start normally.

In this case, the only way to do this is to find a car repair shop or a 4S shop for repair or replacement. If it is not dealt with in time, it will also have a certain impact on the car.

Dear, you're so stupid! I am glad to answer for you, such as if the diesel EFI engine can not be refueled, then the following reasons are mainly considered. First, the intake of the engine is not smooth.

This is often the case when the engine's air filter is clogged or the turbocharger is stuck. So you need to remove the air brake and then check the turbocharger for oil leaks or jams. Second, the mixture of the engine is abnormal.

In this case, the main consideration is that the sensor of your engine is not normal, for example, if there is a problem with the air flow meter or oxygen sensor of the engine, the mixture will be too thick, or the mixture will be too thin, which will lead to insufficient power. Third, you need to consider that your oil supply pressure is not enough. For example, a diesel EFI engine needs to use a high-pressure oil pump to supply fuel, if the high-pressure oil pump is damaged, it will lead to insufficient fuel supply pressure of the engine, resulting in poor engine acceleration, so it needs to be overhauled from the above points.

Looking forward to seeing you again! Have a great day!

Summary. 1. The oil supply is not smooth due to the blockage of the oil circuit.

2. The pressure relief rail pressure of the fuel injector is too low. As a result, the oil supply is not available.

3. The pressure relief rail pressure of the common rail pressure limiting valve is too low, resulting in no oil supply. EFI diesel engine refers to a diesel engine that uses electronic control of fuel injection and emissions. The whole system consists of three parts: sensor, ECU and actuator.

What happens when the diesel EFI engine can't be refueled.

1. The oil supply is not smooth due to the blockage of the oil circuit. 2. The fuel injection is too low. As a result, the oil supply is not available.

3. The pressure relief rail pressure of the common rail pressure limiting valve is too low, resulting in no oil supply for hail. EFI diesel engine refers to a diesel engine that uses electronic control of fuel injection and emissions. The whole system consists of three parts: sensor, ECU and actuator.

Check the oil circuit.

The cause: poor engine starting.

Explanation: 1. Stepping on the accelerator a few times before starting the engine is a habit for many drivers, especially when the car starts cold in winter. However, this starting method is not suitable for EFI cars.

The engine equipped with electronically controlled fuel injection device is different from the ordinary carburetor engine, and its fuel injection control device can automatically adjust the fuel supply according to the temperature and working conditions of the engine, so that the engine can start smoothly, that is, when the cold car starts, the fuel injection control device can automatically increase the fuel supply. Therefore, when the EFI car engine starts, there is no need to step on the accelerator, let alone continuously press it before starting, otherwise the engine will start poorly.

2. Turn on the ignition switch and start switch, the engine cannot be started, and there is not even the unique rotation sound of the engine. There are phenomena such as the starter does not rotate, rotates slowly, and idle.

3. When the start switch is turned to the starting position, the engine cannot be started, and there is no other phenomenon. This kind of failure, first, the key and switch are not connected to the starting circuit due to wear; Second, the starter relay is not connected to the starter electromagnetic switch circuit; Third, the power switch is not connected to the main circuit. There is only a slight "click" sound when starting, and there is no response, which is caused by the issuance of the starting relay.

At this time, as long as you press the tail of the solenoid to force the solenoid forward, the starting circuit can be turned on, so that the engine can be started.

Pro, the speed of the EFI diesel engine cannot be raised, in fact, the throttle can not be added, common reasons and treatment suggestions: 1. Air inlet into the diesel pipeline, if so, the air operation of the exhaust circuit is carried out; 2. The oil circuit is blocked, the oil supply is not smooth, if the inspection is so, it will be replaced or repaired; 3. If the diesel filter is too dirty, if it is checked, it will be replaced or cleaned; 4. The pressure relief valve of the common rail pressure limiting valve of the diesel engine should be carefully grasped and the rail pressure is too low, and if the inspection is so, it will be replaced or repaired; 5. The plunger parts of the fuel unit pump are seriously worn, and if the inspection is so, it will be replaced or repaired and imitated; 6. If the diesel engine control controller (ECU) fails, if the inspection is so, it will be replaced or repaired; 7. If there is a turbocharger installation, the turbocharger impeller is damaged, and if it is checked, it will be replaced or repaired.

Hello, help me to solve the problem of destroying the pants, it is usually normal, it rains or the oil can't be added after the car wash, it is good to start, but the refueling does not respond, and the start without refueling is about twenty yards and will be normal again.

Dear, according to your description, it may be caused by the poor working condition of the electric fuel pump.

Dear, the car can not be fueled after the water is as follows:1. First, check whether the oil pump of the oil tank is normal, or it is possible that the impurities in the oil pump are too much to absorb the oil; 2.

Second, check that the gasoline grille is in good working order. If the gasoline grid does not work, it may also result in a failure to refuel. 3.

If the air intake system is blocked, such as an air filter, check the air intake system and carry out professional repairs; 4.Incorrect valve timing, such as poor sealing of intake and exhaust valves. The original factory solves the problem that the car cannot be oiled, cleans the oil circuit, replaces the gasoline filter, or adds some cleaning additives to the fuel when refueling in Tanqing.
