What is the reason why the car does not catch fire, and what causes the car to suddenly fail to catc

1. Power supply problem: Check whether the AC power plug indicator is on, and first eliminate the problem of the power supply part.

2. Solenoid valve failure: If only the ignition sound is heard during ignition, and there is no solenoid valve "click" magnetic suction sound, it may be: a

The solenoid valve is damaged or aged, the solenoid valve is aging, it will be uncontrolled, and it can be sucked at the beginning of the ignition, and it can catch fire, but then it closes and turns off; b.If the gas pressure is too high or too low, the output pressure of the cylinder pressure reducing valve will be too high or too low in the water heater using cylinder gas, and the water heater cannot be ignited; c.The solenoid valve has dirt.

The solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, and cannot come out, so that the ignition cannot catch fire. Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit is normal, if there is a fault, the solenoid valve cannot be controlled.

3. Electric ignition failure: One of the pulse ignition and controller is faulty, and the water heater cannot be ignited normally.

4. Ignition porcelain needle or induction porcelain needle problem: aIt is very difficult to ignite when the ignition needle is offset or aging, and the ignition needle can be replaced or placed correctly; b.Induction aging, you can polish the induction and place it well (so that the flame can fully burn the induction needle regardless of large fire or small fire).

5. Water pressure problem: aWhen the water pressure is low, the water heater cannot start normally; b.The filter screen at the water inlet is blocked and the water cannot flow normally, so you can clean it up.

6. Failure of water-gas linkage device: aThe eardrum in the water-air linkage valve is aging or damaged, and the micro switch cannot be pushed; b.The micro switch is broken.

7. If the air source switch is not turned on or the air inlet filter is blocked, open the air source correctly and clean the air intake filter.

8. The gas type does not match; For example, if the liquefied gas water heater is connected to natural gas, p In this case, the liquefied gas water heater needs to be changed to natural gas before it can be connected and used.

9. The valve seal is corroded by gas and then swells. Replacement parts.

10. The smoke pipe cannot be exhausted normally. a.If the smoke pipe is blocked, clean up the smoke pipe blockage; b.The smoke pipe is too long and not installed properly.

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

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.

Many people will always have this or that problem with the use of the vehicle after owning a car, and many of them have experienced the situation of suddenly not catching fire. In such a situation, many car owners panic, in fact, it is important to stay calm and check the specific situation.

1. Check the status of the battery.

In most cases, the difficulty of starting the car in winter is caused by the loss of battery power or the expiration of the battery life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out.

2. Change the appropriate engine oil.

In winter, as the temperature drops, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. If it is difficult to start, check whether the oil label is incorrect.

3. Replace the spark plug in time.

After a few years of use, spark plugs are prone to cause problems such as carbon deposition, leakage, excessive clearance, and ablation, which will cause difficulties in car ignition, cold start, and even hot engine start, and often need to be ignited multiple times. Therefore, when driving to a certain number of kilometers or feeling that the vehicle is difficult to start, weak, shaking, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it in time.

The car does not catch fire, and there may be the following reasons:

1. The battery is out of power, which may be due to the loss of power caused by the long-term headlights not turned off or the battery life expires;

2. The gear is wrong, the gear must be placed on the P or N gear when the automatic transmission car starts, and if it is placed on the R or D gear, it will not ignite;

3. The steering wheel is in a locked state;

4. When there is no gas, when the car has no power, it will naturally not catch fire;

5. Circuit or electronic faults.

For cars, there are several reasons why someone can't catch fire, the first is to see if the accident is without gasoline, the second is whether the battery has no electricity, and then there may be engine problems.

The reason why the car does not catch fire may be that your battery is out of power, or it may be that your spark plug needs to be replaced. There are only these two reasons, and there are generally no other failures.

There are several reasons why the car cannot catch fire, the first is to see if there is gasoline, the second is whether the battery has no electricity, and then there may be a problem with the engine, which needs to be further diagnosed whether it is an internal problem of the car or a problem with the control circuit.

If the battery is out of power, it may be due to the loss of power caused by the headlights not being turned off for a long time.

Or the battery life expires, and the installation of xenon headlights, high-power audio, etc., is caused by vehicle circuit failure.

The situation of the vehicle without power is easy to check, and you can know by pressing the horn.

The gear is wrong, and when the automatic transmission car starts, the gear should be placed on the P gear or N gear.

There are several reasons why the car does not catch fire.

1. There is a problem with the quality of the oil.

2. The external ambient temperature is too low.

3. There is a problem with the spark plug or fuel injector.

4. The car is old, and the sealing performance of the cylinder and piston has changed.

5. The battery of the car is insufficient.

Hello, there are many reasons for not catching fire, the most common reason is that the battery is losing power, you can check the voltage of the car, if the voltage is too low, you need to use the rescue service to connect the phone,

The reason why the car won't catch fire. The reasons why the car does not catch fire are generally as follows:

1. The battery is out of power or the fuel tank is out of oil;

2. The gear is wrong or the steering wheel is locked and cannot be started;

3. Automobile circuit or electronic faults, such as spark plug damage, fuse blowout, oil pump failure.

4. Oil problems, the engine cannot work normally due to bad fuel, etc. If the starter is functioning properly when the ignition starts, it is not because the battery is dead, but for other reasons. There are two common reasons.

One is that the idle motor or throttle is seriously damaged or carbon deposits, and the other is that the gasoline pump is damaged. Ignition failures are now rare because each spark plug is an independent ignition coil that does not break at the same time. How to tell if the idle motor or throttle is faulty, just ignite the ignition and release the throttle repeatedly.

If the idle motor fails, you can start it by pressing the accelerator. There are also two situations where ignition cannot be achieved due to improper operation, which is occasionally encountered. It is an automatic transmission car that ignites at point D, stops temporarily at point D, and then turns off directly.

When restarting, I forgot that the gear was not in P gear, and the ignition could not be started. The second is manual blocking. Vehicles that need to press the clutch ignition forget to press the clutch, or the clutch does not start because the foot pad is too thick.

In both cases, there was no sound when the ignition was started and there was no response when the ignition was started. In this unresponsive situation, the first thing to consider is the issue of the P gear and clutch. The vehicle battery is dead or damaged, the battery life expires, or the battery is damaged when the vehicle is parked for a long time; The battery power loss may be due to the fact that the ignition switch of the car is turned on, and when the vehicle is not started, the headlights are turned on for a long time, and high-power entertainment systems such as high-power audio are always used.

The sudden failure of the car to catch fire is usually caused by the following reasons:

1. Battery failure.

This is a very common fault, but how can we tell if it is a battery failure? First ignited, the car engine will make a "da-da-da" sound, and it will catch fire as soon as it hits. If you hear the "da-da-da" sound, the car still doesn't catch fire, and the battery indicator on the car's dashboard also lights up.

At this time, the battery is out of power.

When the battery is out of power, if it is an automatic car, we can seek help from other cars, the two cars are in the state of turning off, connect the positive and negative poles of the two cars with wires, and then start the full tram, step on the accelerator empty, and then enter the tram to ignore. If it is a manual transmission, we can borrow a human-powered cart, of course, there is a ramp nearby, and you can also use the ramp to slide to start, or the front car can use the tow rope to pull the car behind.

2. The spark plug is blocked.

If the vehicle starts successfully, but there is obvious frustration when starting, then we should observe the operation of the engine, and there is continuous or intermittent shaking, it is likely to be caused by the spark plug. At this time, you can start with the spark plug to see if there is a hidden danger, so that it can be replaced in time.

3. Gasoline pump pressure relief.

Many car owners will encounter the situation that the first ignition fails, and the second time it will succeed. This situation should not be taken for granted as the cause of the battery's power loss, in fact, it is mostly related to the pressure relief of the gasoline pump. After a long period of use, the gasoline pump will wear out internally, which will lead to insufficient fuel supply pressure and difficult ignition.

In this case, replacing the petrol pump will solve the problem.

Hello, I'm helping you sort out the answer to your question, please wait a while The vehicle suddenly can't catch fire, this is to open the key when starting, if the instrument light is not on, including whether the horn is working, in this case, you need to check the battery, there may be a battery loss caused by power loss, if you open the key is the light on the instrument is also on, the battery is electrified, and the engine can not start, in this case you need to check the starter, to see if there is a problem, The solenoid switch on the starter needs to be checked.

The question should be a starter.

In this case, you need to check the solenoid switch on the starter. The main job on the starter is that there is a problem with the electromagnetic switch inside.

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:1The 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!

Hope, thank you.

Hello, there are many reasons for not catching fire, the most common reason is that the battery is losing power, you can check the voltage of the car, if the voltage is too low, you need to use the rescue service to connect the phone,

There are many faults that will cause the ignition to be fired, first eliminate the problem of electricity, see if there is electricity, and then see if there is oil, a little check can not be in a hurry, it is really not possible to trouble the car repair shop.
