The car does not catch fire and does not respond, what is the reason why the car does not catch fire

1. The first thing to confirm is that the battery is still powered, because when the battery is out of power, there will be a phenomenon of ignition and no response.

2. Check the belt of the engine, whether it has been used for a long time and has been aging, so when ignition, the belt slips and cracks, resulting in the car not catching fire.

3. If there is a failure problem in the ignition system, when the ignition coil or spark plug is aging, it will cause this kind of problem, and the solution is to replace the new spark plug.

4. There is a problem with the oil supply system, when the pressure of the oil pipe is too low and the oil pipe is blocked, the oil supply will not go up, so it will not be able to hit when ignition.

5. Check whether there is any leakage in the air intake system, such as throttle valve, idle control valve pipeline, etc.

The reasons why the car engine does not catch fire are as follows:

1. The car battery is insufficient or the fuel is insufficient, which is the easiest item to check, and it is also the most likely to cause the car to not catch fire. The amount of fuel is easy to judge, the ignition key goes to the ON gear, one key to start the model without stepping on the brakes, press the start button twice, turn on the headlights, and the lights obviously change from strong to weak or simply not bright. Then press the horn, the horn sound is significantly weaker than usual, or it does not sound, which can be judged as the battery is insufficient.

Once these two situations occur, then you can choose to ask for help from surrounding car owners according to your own conditions, and apply for emergency measures such as taking electricity, borrowing fuel, and trailers.

2. The steering wheel can not be started when it is locked, which is an ordinary anti-theft function that many cars have, after pulling out the car key, the steering wheel is not back to the right or has to rotate, it will cause the steering wheel to start the self-locking function, the steering lock pin and the steering column are buckled together, the steering wheel can not move, and it can not catch fire.

The solution is very simple, that is, to twist the key while shaking the steering wheel, otherwise it is impossible to twist the key even if it is broken.

3. Check the gear of the car, under normal circumstances, P gear or N gear is the correct gear when the automatic transmission car starts. If the owner is careless and puts the gear in R gear or other gears, the result will not only be unable to ignite, but also cause potential safety hazards.

The car engine is powered on and does not respond.

1. The whole car is powered on and does not respond, and the instrument light is dim: under normal circumstances, when the dashboard self-test before starting the car, if the battery light is on, and it is obvious that the brightness of the dashboard is not as bright as under normal circumstances, it can be judged that the battery is losing power, or it has reached the service life.

Sometimes the instrument is not displayed, but when starting the car, you can clearly feel that the engine rotation frequency is extremely slow, which is also a precursor to the battery loss, and the best solution at this time is to change the battery in time.

2. The battery does not lose power, and the engine starts normally: after pressing the ignition, the engine sound is normal, and there is no obvious dimming of the screen or dimming of the indicator light in the car when working, indicating that there is no problem with the battery and the engine. If the fire does not ignite at this time, there may be a problem with the high-pressure oil pump, the trip computer, or the engine is not fueled, so this situation can only be called a tow truck rescue.

There are many times in life that the car does not catch fire, what is the reason, the rabbit takes you to understand the reason, generally the car does not catch fire and do not need to worry, sometimes it may be a problem during operation, the most common is that the steering wheel is locked.

Is the battery charged? Whether the starter motor is working when it starts, the first two are all fine, check whether the fuel injection signal and ignition signal are there, there are too many things, in short, the circuit is eliminated, and then the mechanical fault is eliminated.

Turn on the key and wait for the computer to finish the self-test before ignition, because the gasoline pump starts to pump oil to the nozzle during the self-test! The engine oil should be changed, and the spark plug should be checked once every 10,000 kilometers. It is recommended to replace the spark plug, and the original spark plug is 16 pieces!!

It may be that the battery is dead, find a car to dock the circuit, drive to repair the car after the ignition is successful, and never turn off the engine halfway. Or just call a trailer.

Check the battery level, crisper box, and oil level.

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

There are many reasons why a car does not ignite:1. The battery is dead; 2.There is a problem with the oil circuit; 3.There is a problem with ignition; 4.The anti-theft key is dead.

The specific reasons why the car won't catch fire are as follows:

1.Battery. When an engine is ignited, the battery is the basis for power.

If the battery does not power the ignition system, the natural car will not ignite. The main factors that lead to battery power failures are continuous power consumption, over-discharge, and electrode corrosion. In fact, these three problems are completely avoidable in the daily use of the vehicle.

2.Hydraulics.

When it comes to the oil system, there are three more issues that can cause the vehicle to fail to catch fire. First, there is no oil; Second, there is a problem with the oil pump; Third, the oil circuit is blocked. If there is no oil, there is an oil gauge on the dashboard.

3.Ignition system.

The ignition system is nothing more than a starter motor, spark plugs, ignition control bus, and ignition coil. The most likely problem is the starter motor and spark plug. If the circuit in the car has not been replaced or the engine has been overhauled, the probability of problems with the ignition control bus and ignition coil will not be too large, unless the car is too old and the circuit is seriously aged.

Damage to the starter motor, i.e., failure of the meshing device, solenoid valve, gear, bushing, motor bearing. Spark plugs, as long as the normal maintenance reaches the mileage, should be replaced with a new one.

4.Anti-theft keys.

An anti-theft key is a chip with a coin cell battery and a case. Battery failure test method: The lock can be unlocked every 8 9 meters. If you need to get close to the car every time you unlock or lock the car, quickly change the battery for the key.

To sum up: I usually drive to dig a few points. When the time is up, you must repair it on time. In addition, you should also pay attention to routine maintenance and inspections. If the ignition does not respond, you need to go to the 4S shop to check the repair.

Many car owners will encounter the situation that there is no response when starting the car for no reason, which is basically unrelated to the fuel system of the car. In this article, we will explain to you three ways to solve the problem of starting the car not responding.

The battery is dead.

Some car owners forget to turn off the electrical equipment on the car when they get out of the car, so that the battery is exhausted, and eventually leads to no response when starting the car, at this time we can use the way to restart the vehicle, about 30 kilometers, the engine can be charged for the battery.

The battery wiring ring is loose.

The engine compartment often enters the cat, it is possible that the cat touched the wiring ring of the battery in the process of heating, loosened or removed the wiring ring on the battery, only need to open the cabin and tighten it.

The trip computer is down.

Many cars have a display after turning on the power, but they can't start the vehicle, which is caused by the shutdown of the driving computer, we only need to unplug the battery cord for about 30 seconds, and plug it back in, whether it is a fuel vehicle or a new energy vehicle. (This is generally more common in new energy vehicles).

The battery mains fuse is damaged.

When the main power supply fuse of the car battery is broken, it can not be found on the way, because there is a generator in the power supply, so it is good when it is parked, but it is not reflected when it is restarted, at this time we can only go to the maintenance point to replace the fuse to solve the problem.

Some new energy fuses with quality problems cannot withstand high temperatures, and fuses will also blow due to thermal expansion and contraction when parking.

The car could not start, and the ignition did not respond, there was a serious battery power loss, carbon deposition and ablation of the spark plug, serious wear of the carbon brush of the starting motor, and damage to the starting relay.

If it is in a cold area, most of the ignition does not respond due to the lack of battery starting capacity, due to climatic conditions in winter battery performance will be significantly reduced, the battery that has been used for about 3 years is close to scrapping should be replaced in time. The same oil will also be affected to a certain extent, poor fluidity in winter, it is recommended to warm up for a few minutes after landing, and it is recommended not to rotate too high at the beginning.

If the vehicle ignition does not respond, do not continue to ignite frequently, which will easily lead to serious battery loss, and can not start again, the practice is to try to start 3 times without success, should wait 3-5 minutes to try again.

There are several reasons why the car won't start: one. No oil. Two. Power. Three. No air intake.

Let's analyze these four items approximately:

One. No oil.

The reasons for the failure are:1The oil pump relay is working poorly. 2.The oil pump is not working well. 3.Out of gas.

Fault Detection: 1Detection of oil pump relays:

Turn on the key switch and don't hit the motor, you will hear a click, which means that the relay is working properly! If there is a continuous clicking sound, check whether the tie wire is loose. If the relay is judged to be damaged, the light relay can be interchanged with the oil pump relay.

Drive to the repair shop and buy a new relay.

2.Detection of oil pump: Generally, it is checked with an oil pressure gauge, because it is self-excluded.

There is no oil pressure gauge! The easiest way to do this is to remove the tubing and turn on the key switch on the position. Do not start the motor.

If the oil pipe is injected, it means that the oil pump is normal. On the contrary, it is not normal.

Two. Power. Cause of failure:

1.The head of the battery pile is loose. 2.

The high-voltage ignition coil is damaged. 3.The cylinder line is damaged.

4.Whether the starting relay is plugged in properly or not, it is damaged. 5.

Whether the insurance is burned out. 6.Whether the motor is working properly.

7.Whether the main output cable of the computer case is loose.

Fault Detection: 1Detection of loose battery pile head: observe whether the instrument is displayed, if the whole car has no electricity, open the hood, and observe whether the battery pile head connection is loose and oxidized. Loosen it with a wrench, and pour boiling water on the pile head for oxidation.

2.Detection of ignition coil: You can use a multimeter to check the resistance value of its primary and secondary coils, which should be within the conforming range, and the secondary resistance should be larger than the primary resistance!

But that's not sure if it's in good condition! Unplug the cylinder wire, observe it for flashover, and see if there is any leakage in the insulation! The jumping fire should be blue, and the sparks are thick and long!

3.Detection of steel wire: check the resistance value with a multimeter, which should be within the load range. Unplug the cylinder cord and observe it for a flashover. Or skip the fire and replace.

4.Detection of starting relay: There is a problem with the general relay, and there is no response when hitting the motor. Plug and unplug the relay again to see if it starts normally! Replace the relay or motor shorted.

5.Detection of the fuse: Open the fuse and observe whether the fuse indicator is normal and whether the fuse is burned. Replace the fuse.

6.Motor detection: mainly listen to whether the sound of the motor is normal. If the carbon brush of the motor is severely worn, it can be temporarily activated by hitting the motor with a hammer. Go back to the repair shop for replacement.

7.Whether the main output line of the computer box is loose: check whether the plug-in of the computer box and its wiring and each sensor is loose. Fastening is recommended.

Three, no air intake.

Cause of failure: Damage to the eccentric wheel and wear of the eccentric shaft, resulting in the intake and exhaust valves cannot be opened and closed.

Troubleshooting: Call a tow truck!

If it helps you, please light it up, thank you.

It must be out of power, and the battery for about a year can be charged by a car repair shop, and the battery can be replaced for about three years. If you can't start it, you can find an insurance company to take the electricity, free of charge.

The reason why the car does not catch fire and does not react:

1. Battery, the battery is the basis of power supply when the engine is ignited, and the battery does not supply power to the ignition system, and the natural car will not catch fire. Several factors that cause the battery to not supply power are mainly continuous power consumption, over-discharge, and electrode corrosion. In fact, these three problems can be completely avoided when the vehicle is used in daily use;

2. The oil circuit system is also three kinds of problems for the trapped Shengxiang oil circuit system, which can cause the vehicle to not catch fire, one is out of oil, the other is the oil pump problem, and the third is the oil circuit is blocked. If there is no fuel, there is a fuel gauge on the dashboard, in addition to looking at the tachometer and speedometer when driving, take a look at the fuel level Wang Bo meter, should refuel. If the oil pump or oil circuit is blocked, it is recommended to find a professional car repair place to see;

3. The ignition system, the ignition system, is nothing more than the starting motor, spark plug, ignition control bus, ignition line laughing mu circle. If you have not changed the circuit in the car or overhauled the engine, the probability of problems with the ignition control bus and the ignition coil is not too great, unless the car is too old and the circuit is aging more seriously. Damage to the starter motor means that there is a problem with the gear, solenoid valve, gear, bushing, and motor bearing.

Spark plugs, as long as the normal maintenance to the mileage, should be replaced with a new one.

Pacific Automobile Network] The reason why the car ignition does not respond: 1. There is no gas. The fuel gauge shows that it is below the red line, so it will naturally not ignite; 2. The battery is out of power.

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

4. No antifreeze is 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.

5. Excessive carbon deposition in vehicles. Too much carbon deposition will also cause the vehicle to not catch fire, and the solution is to reduce carbon deposition by running at high speeds 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.
