What s wrong with the EFI truck not catching fire, and what is the reason why the EFI truck can t ca

Let's see if there's something wrong with the PC version? Remove the battery and put it back on, OK!

Change the spark plug. Go buy a better spark plug.

If there is no oil in the tank or the battery is empty, it will not ignite.

The oil pump relay may be broken, replace it with an oil pump relay.

Check whether the storage electromagnet has electricity and whether the fuel is sufficient. Then see if the fuel injection ignition is normal.

There are many reasons for this, depending on the situation, it is recommended to let the car mechanic take a look.

It could be air, or the oil circuit is blocked.

What is the reason why the car does not catch fire?

1. The temperature is too low, which generally occurs in winter, because the viscosity and speed of the automobile oil are reduced in such an environment, but the ignition energy of the battery is reduced, so that the flammable gas cannot be formed, and it is difficult to ignite;

2. The spark plug is damaged and does not work, the spark plug is the key component of the automobile ignition system, and the ignition system of the vehicle is the key to the work of the car heart, so whether the spark plug can work normally is related to the working performance and efficiency of the vehicle;

3. The battery is out of power. It may be due to the loss of power caused by the long-term headlights not turned off or the battery life expires, it is generally recommended to replace the battery in time after 2 years;

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

How to exhaust air from EFI diesel engine?

The exhaust of the EFI fuel engine must be carried out when the car is turned off. On the side of each diesel pump there will be a manual exhaust device, which is continuously pressed by hand until the oil is sprayed. If you find that the fault light is on after exhausting, you need to use a decoder to remove the fault, so that all the fault lights will become normal.

Hello 1The first reason is that the starter itself is damaged, the service life of the starter is generally about 100,000 kilometers, and if the use time is too long, the carbon brush is easy to be damaged, which will also cause the starter to fail to start.

The second reason is that the battery voltage is not enough to start the starter.

The third reason is that the gasoline pump is damaged and the fuel cannot be supplied.

The fourth reason is that the gear cannot be ignited when hung on the D gear, which is the self-protection mechanism of the car to prevent the car from rushing forward after ignition.

The fifth reason is that the car's engine speed sensor (crankshaft position sensor) is damaged, resulting in the vehicle not having a high-pressure fire, which makes the car unable to start normally.

If the EFI vehicle does not respond to the ignition, it may be that the starting voltage is insufficient, that is, the battery is out of power. Secondly, boot failure is also an important cause. It is advisable to inspect the repair from both aspects.

1. The fuse is burned 2, the fuel tank has no fuel 3, the fuel tank outlet pipe is blocked 4, the fuel system has air 5, the starting relay is bad 6, the fuel pipe or fuel filter is blocked 7, the fuel injection is poor or the injection pressure is too low 8, the fuel injection advance angle is incorrect 9, the electrical equipment joint is loose 10, the controller EUC power supply is abnormal 11, the battery is insufficient, the flywheel speed is not enough 12, the starter motor is damaged 13, the diesel engine temperature is too low 14, the Toulon speed sensor installation clearance problem or the sensor is damaged 15, cam, The power supply of the crankshaft sensor or temperature and pressure sensor is short-circuited to the ground 16, the fault diagnosis switch is opened before starting 17, the ECU of the controller is damaged (the internal components are damaged) 18, the phase is incorrect (timing) 19, the starting oil volume is too small 20, the control program is not matched 21, the back pressure valve is invalid 22, and the ground wire is brokenMore diesel EFI maintenance.

If there is a fault, you should go to a repair shop, let the professional master find the reason, and don't mess around yourself.

There are many reasons, generally check the circuit part first, then check the oil pressure, and finally check the mechanical part.

Summary. Hello. There are several reasons why the EFI motorcycle cannot catch fire:

1. The injection unit is damaged, or the fuel injection is not injected or the 5A fuse is blown out; 2. Poor contact of corner mark signal sensor; 3. The magnetic field of the machine is not strong; 4. Battery failure; 5. There is a problem with the ignition system line; 6. The oil circuit is not smooth; 7. Poor gasoline oil quality; 8. Engine failure.

Exclusion method: 1. When opening the car key, if there is no injector self-test sound, visually check whether the fuse is blown, and replace the fuse if necessary. If there is a self-test sound, remove the injector (keep the connector connected), press the start button, check the fuel injection status, and replace the injector if necessary.

2. Check the connection of the corner markings and fix them. 3. Check the strength of the magneto signal.

What's the deal with the EFI motorcycle that won't catch fire?

Hello. The reasons why the EFI motorcycle cannot catch fire are: 1. The injection unit is damaged, or the fuel is not injected or the 5A fuse is blown out; 2. Poor contact of corner mark signal sensor; 3. The magnetic field of the machine is not strong; 4. Battery failure; 5. There is a problem with the ignition system line; 6. The oil circuit is not smooth; 7. Poor gasoline oil quality; 8. Engine failure.

Exclusion method: 1. When opening the car key, if there is no injector self-test sound, visually check whether the fuse is blown, and replace the fuse if necessary. If there is a self-test sound, remove the injector (keep the connector connected), press the start button, check the fuel injection status, and replace the injector if necessary.

2. Check the connection of the corner markings and fix them. 3. Check the strength of the magneto signal.

If there is a sound, it will not start.

If the oil pump of the oil supply system is damaged or the injector is faulty, replace the injector.

When opening the car key, if there is no sound of the oil pump running, check whether the fuse of the EFI system is blown and whether the oil pump relay is damaged, and replace the fuse or relay if necessary. If there is a running sound, remove the injector (keep the connector connected), press the start button, see if the injection condition is well atomized, and replace the injector if necessary.

1: The steering wheel is not in a deadbolt state. The solution is simple, as long as you hit the steering wheel hard and twist the key at the same time, you can generally unlock the steering wheel lock quickly, and the ignition is an instantaneous thing.

2: Did you not return the gear to P when you parked? Think about it, if the D or R gear can be ignited, the jump of the vehicle at the moment of ignition is undoubtedly a huge safety hazard.

Therefore, for automatic transmission vehicles (AT, CVT, AMT), the manufacturer will preset this mode, and repeatedly tell in the manual: make sure that the gear is in the P gear position when ignition. 3：

The key is in the car, but the instrument always shows 'key matching error', which is likely to be the power loss of the smart key, and the starting system cannot sense the weak radio waves emitted by the key. Therefore, it is recommended to pick up the smart key and put it on the start button, and then press the button to start. 4：

Check if the battery has power. If the ignition is not ignited, it may be due to the loss of power or the expiration of the battery life due to the long-term headlights have not been turned off, and the battery is generally replaced in time according to the maintenance manual. 5：

See if there's oil. If the fuel gauge shows that it is below the red line, it will not ignite. At the same time, pay attention to the quality of the oil.

There have been car owners who found that there was water and mud in the fuel tank after disassembling the car, and with such oil, it is impossible for the car not to break. 6: Some car owners add water or inferior antifreeze to the car without antifreeze, resulting in a particularly cold winter, resulting in the entire waterway being frozen, the engine being frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

One is to observe the fuel gauge or fuel level warning light, if the fuel tank is insufficient, you should fill up the fuel before starting the engine. Some people say, this is not a fool, such a simple thing is still taken out! Don't be so complacent, this is not only there, but it is always there!

In our maintenance work, there are many cases of forgetting to refuel and causing it to be difficult to start. One is that the oil runs dry, and the other is that the oil is too little, because many EFI motorcycles have oil pumps, too little oil may make it difficult to form oil supply pressure, and the oil pump needs to be buried in the gasoline to dissipate heat, and too little may burn the oil pump.

The second is to check the ignition system. Unplug the high-voltage lead at the end of the spark plug and make its end 5-7mm away from the cylinder block, press the start button, and use the starter to drive the engine to run to make the spark plug jump fire. If the high-voltage spark is weak or there is no fire, the wiring connection of the ignition system and the technical condition of the ignition coil, ignition controller and other components should be checked.

If the high-pressure spark is normal, you can check whether the spark plug is good first, and then check the next step when the spark plug is normal. As a car owner, the focus is to check the connection, and experienced ones can make further judgments according to the brightness of the spark and the color of the spark plug.

The third is to observe the engine electronic control system fault warning light, if there is an alarm, indicating that the electronic control system is faulty, the fault code should be read and according to its instructions to eliminate the fault, of course, as the owner, there may not be a professional fault diagnostic instrument, but it is necessary to spare a simple detector of more than 100 yuan, such as the Bluetooth EFI detector of [fingertip motorcycle]. The main components that usually affect the starting performance of the engine are: crankshaft position sensor failure, coolant temperature sensor failure, intake pressure sensor, etc.

As a rule of thumb, when a fault indicates a sensor failure, special attention should be paid to whether the sensor line and connector are well conducted. This is because such problems are more likely to occur than actual sensor failures.

The solution to the EFI motorcycle that does not catch fire is:1Observe the fuel gauge or fuel level warning light

If the fuel tank is insufficient, the engine should be started only after the fuel tank is full. 2.Check the ignition system:

Unplug the high-pressure lead at the end of the spark plug and make the end 5 to 7mm away from the cylinder block, press the start button, and use the starter to drive the engine to run. 3.Observe the engine electronic control system fault warning light

If there is an alarm, it means that the electronic control system is faulty.

Questions. Where to check if the electronic control system is faulty.

Where to check if the electronic control system is faulty.

Check if there is a fault light on the meter.

Questions. High voltage electrolysis.

High voltage electrolysis. Yes.

Yes. The high-voltage power deficiency is caused by the starting voltage of the battery being too low, and the battery needs to be replaced.

Questions. Does not catch fire have anything to do with overtaking the clutch?

Does not catch fire have anything to do with overtaking the clutch?

This generally doesn't matter, mainly due to insufficient ignition voltage.

Questions. Where else is it easy to break.

Where else is it easy to break.

The ignition coil is also prone to breakage.

1. The battery voltage is lower than 10V, resulting in insufficient starting energy. You can try to start with the wire.

2. The starting motor is seriously worn and the motor is bored.

If the instrument light is normal after the key is opened, the manual transmission car can try to start the cart. Don't rule out the automatic car yourself, if the insurance is complete, call the accident-free rescue tow to the repair shop for another check.

The automotive electronic ignition system is completely different from the mechanical ignition system, it has an electronic control device for ignition, and there are ignition control curves (maps) required by the engine under various operating conditions. The working status of the engine is judged by a series of sensors such as engine speed sensor, intake pipe vacuum sensor (engine load sensor), throttle position sensor, crankshaft position sensor, etc.

Find out the ignition advance angle required by the engine in this working state on the map, and carry out ignition according to this requirement. Then the above ignition requirements are corrected according to the knock sensor signal, so that the engine works at the best ignition time.

The current popular Atkinson engine changes the compression ratio by adjusting the intake time and ignition time to achieve the purpose of fuel saving.

Generally, the switch or line is faulty: 1. After the switch or line fails, observe whether the circuit switch is back and whether the fault light is on; 2. The switch problem is often not paid attention to, and it should be checked first when you get on the car; 3. It may also be that the solenoid valve of the high-pressure oil pump is out of order, and the neutral gear can be turned off after the failure to increase the speed; When the switch is good, there is no problem with the line but still can't ignite, it is the failure of the high-pressure oil pump solenoid valve, just check the high-pressure oil pump solenoid valve.

Reasons why the diesel EFI truck does not catch fire:

1. After the switch or circuit fails, observe whether the circuit switch is back and whether the fault light is on;

2. The switch problem is often not paid attention to, and it should be checked first when you get on the car;

3. It may also be that the solenoid valve of the high-pressure oil pump is out of order, and the neutral gear can be turned off after the failure to increase the speed;

4. When the switch is good, there is no problem with the line but it still can't catch fire, it is the failure of the solenoid valve of the high-pressure oil pump, just check the solenoid valve of the high-pressure oil pump.

A faulty starter or battery can make it difficult to start, or even not start, when the engine is in good order. In such a situation, it is necessary to first understand the use of the starter and battery, so as to roughly determine the fault location. The EFI diesel engine is a diesel engine that electronically controls fuel injection and emissions, that is, the EFI diesel engine.

For this case, it is generally possible that the battery is due to a loss of power, so it is recommended to check it. The injection system of an EFI diesel engine consists of three parts: sensor, ECU (computer) and actuator. Its task is to electronically control the fuel injection system, and realize the real-time control of the fuel injection volume and the fuel injection timing with the operating conditions.
