What should I do if the car starts and doesn t catch fire?

This phenomenon is generally a "broken" fault of the battery.

There is a clicking sound indicating that the motor can be started, first check whether the battery is powered, and then check whether the oil is **.

Common reasons why a car won't catch fire.

1. The battery loses power.

In addition to the quality and life of the battery itself, the loss of battery power is generally caused by the owner's own improper use, such as forgetting to turn off the headlights when parking, and too many external electrical appliances. If the starter does not work when ignition, it can basically be determined that it is caused by the battery loss.

Solution: Usually pay attention to the electricity in the car, connect the external driving computer, external display screen, etc. remember to unplug the power when getting off the car, and remember to turn off all the lights. There is also to pay attention to the indicator light on the dashboard in time, if the battery fault light is always on when driving, go to the repair shop or 4S shop as soon as possible to deal with this problem, the replacement and replacement, the maintenance and maintenance.

2. The smart key loses power.

This question is only for cars with a push-start function. When your car key is close to you, but it can't start when you press the one-button start button, and the smart key fault light on the dashboard is always on, then your smart key must be losing power.

Solution: Some models have a one-button start function while retaining the design of key start, so that you can use the key to start the car when your key is out of power. If the car happens to start without a key, you can try to stick the key on the start button and then press the start button, if it still doesn't work, then you can only choose to replace the battery for the smart key first.

The first situation: if there is no problem at the beginning, and the starting time is getting longer and longer, until one day it suddenly fails to ignite, it should be that there is a problem with the ignition system or fuel supply system of the engine, and in this case, it is necessary to find a professional car repairer to repair it.

In the second case, if the ignition start has been very good, and suddenly one day it is better, and the start cannot be started, it is likely to be a problem with the battery.

Battery power loss: that is, the battery cannot be supplied normally. If you forget to turn off the headlights when parking, and there are too many external electrical appliances, the battery will lose power.

Usually pay attention to the car specifications, get out of the car to turn off all the lights, if you find that the battery fault light on the dashboard is on, find a professional to repair as soon as possible.

Insufficient voltage: The reason for not having enough voltage may be because:

1. The battery time is too long, which leads to aging, and the stored power becomes less; 2. The car listens to songs or turns on the air conditioner when it is not started. Some car owners in the car in order to wait for someone, do not twist the key to the end, turn on the air conditioner, listen to songs, this power consumption is particularly powerful, the battery is very easy to run out of power. In these situations, you should also contact a professional for help.

The third case: if the headlight can be used normally, then it is most likely that the internal guard coil of the magnetic switch of the motor is open. In this case, the motor magnetic switch should be replaced.

What is the reason why the car battery has electricity but can't start.

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 worker searched for the first defect. 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 damaged, the light relay can be interchangeable 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 short.

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!

Hello, there are several reasons for this: battery loss, gasoline flow blocked, ignition system not working well, valve glue, exhaust pipe freezing.

The specific cause analysis and solutions are as follows:

1) battery power loss: low temperature in winter and individual electrical equipment will cause the vehicle to be unable to start, especially in winter long-term dry short-distance low-speed use, the battery voltage will be lower than the rated value, start and can not operate normally, if there is a occurrence, please call the service station rescue**, or find the car right, or temporarily on fire, and then must go to the service station to replenish the battery repentance charge;

2) Gasoline flow is blocked: this situation mostly occurs in the morning when the temperature is particularly low, which is caused by the long-term dirt of the fuel pipeline, and when the temperature is particularly low, the water and debris are mixed so that the fuel pipeline is not passable, and the result can not be started, emergency method: put the car in a warm environment, and the car can start after a while; or use the method of cleaning the oil circuit to completely solve it;

3) The ignition system is not in good working condition: especially in cold weather, due to the low intake temperature, the fuel is not well atomized in the cylinder, if the ignition energy is insufficient, the result will be flooded, that is, too much fuel accumulates in the cylinder, exceeds the fire limit concentration and can not land, emergency method: you can unscrew out the spark plug to wipe off the oil stain between the electrodes, and you can get on the car after installation;

4) Valve gelatinization: winter car, especially after the use of unclean gasoline, the gum in the gasoline will not be burned in the intake, exhaust valve and near the combustion chamber, in the cold morning will cause hard starting, or even not fire, emergency method: you can drop some oil into the combustion chamber with the eggplant hole, generally can start;

5) exhaust pipe freezing: the appearance of the characteristics of the fog cylinder pressure, oil supply and power supply normal, do not hit the car, this situation is easy to occur in the use of particularly low frequency of vehicles, the engine after combustion of the water vapor in the exhaust pipe of the muffler frozen, for a long time, affect the exhaust, serious can not start, solution: put the car in a warm environment, ice can be started naturally.

Hello dear, the following answers have been made to your questions, and I have helped you sort it out! That's it, dear!

When the vehicle does not ignite and has a clicking sound. This condition is generally caused by the following reasons:

The first way is to confirm whether the battery voltage is too low, you can turn on the headlights and some electrical equipment, and confirm whether there is a change in the brightness and darkness of the instrument and indoor lighting during the start-up process. Because the current consumed at the moment of starting is very large, when the old bottle of the slag electric shed is insufficient, it is unable to drive the engine to reach the starting speed and cannot land, and the chain of the magnetic bag and the starting relay is repeatedly sucked together, resulting in a clatter sound.

The second is that there is too much carbon deposition in the intake pipe, too much carbon deposition in the throttle and idle motor, so that the high slag of the engine can not reach the air-fuel ratio of the required beam, resulting in the vehicle can not start, can not talk about the car, and the repeated suction of the magnetic bag and the starting relay produces a clattering sound.

The third type of fuel supply in the mountain fuel system is insufficient, which is basically the same as the factor of excessive carbon deposition in the incoming poor trachea, and it is also unable to achieve the mixture air-fuel ratio required by the engine, resulting in the failure of the vehicle to start.

Fourth, the starting motor or related circuit fault, the magnetic coil can not maintain the suction state, can not provide the starting torque, so it will cause the engine to fail to start, and the bird is clattering and clicking.

The fifth dry macro ignition system failure, this will directly cause the engine to fail to start, if the key door has not been in the starting gear, the starting relay is good round and repeatedly engaged, there will also be a clicking sound.

Questions. <>

<> can't hit the fire.

There was a clattering sound.

What is the reason.

The first way is to confirm whether the battery voltage is too low, you can turn on the headlights and some electrical equipment, and confirm whether there is a change in the brightness and darkness of the instrument and indoor lighting during the start-up process. Because the current consumed at the moment of starting is very large, when the old bottle of the slag electric shed is insufficient, it is unable to drive the engine to reach the starting speed and cannot land, and the chain of the magnetic bag and the starting relay is repeatedly sucked together, resulting in a clatter sound.

The second is that there is too much carbon deposition in the intake pipe, too much carbon deposition in the throttle and idle motor, so that the high slag of the engine can not reach the air-fuel ratio of the required beam, resulting in the vehicle can not start, can not talk about the car, and the repeated suction of the magnetic bag and the starting relay produces a clattering sound.

The reasons why the car will not start are generally as follows:

The battery is faulty and cannot store power. If only the sound of the starter can be heard when starting the car, then it is likely that the battery is losing power and cannot be started.

The starter motor malfunctioned and could not drive the flywheel to turn. Check if the starter motor is working when starting the vehicle.

The ignition system of the vehicle failed. Unplug the ignition high-voltage line on the engine, insert the old spark plug or other pen-shaped metal rod into the spark plug cap, put the spark plug body or metal rod body close to the metal part of the engine, start the engine to observe whether there is a high-voltage flashover, and check the ignition system if not.

The vehicle's fuel supply system failed. Unplug the oil pipe joint on the upper flush bend of the engine, turn on the ignition switch, and when the instrument light is on (the starter is not running), observe whether there is any pin stuffy oil flowing out. If there is oil outflow, there is no problem with the oil supply system, and if there is no oil, continue to check.

This may be due to engine ignition, which may be overheating or there is a problem with the spark plug, it is recommended to check the ignition coil and spark plug.

The battery hangs, it will cause a series of faults to pop up, find a car to take the power or replace the battery to start the car, if there is a fault code, you need to go to the 4S shop with a special computer to test the cause of the fault and crack the filial piety to eliminate!

Hello, it takes some time to type, please be patient and wait a while. [smiles].

Hello, glad to answer for you. When the car is ignition, it can't start, probably because the battery is "broken" and faulty. The common reasons why a car won't catch fire are as follows:

1. Battery power loss: Battery power loss can be said to be one of the most common reasons why the car cannot be started. 2. The smart key loses power.

This question is only for cars with a push-start function. ”

I hope the above can help you, I wish you a happy life, and if you are willing, give a thumbs up.

There may be several reasons why the car does not catch fire and makes a clicking sound:

1. The starter motor is faulty and cannot drive the flywheel to rotate. When starting the vehicle, check whether the starting motor is working.

2. The battery is faulty and cannot store power. If you can only hear the sound of the starter when starting the car, it is likely that the battery will not start due to a loss of battery power.

3. The fuel supply system of the vehicle is faulty. Unplug the oil pipe joint on the engine, turn on the ignition switch until the instrument light is on, and observe whether there is oil flowing out. If there is oil outflow, there is no problem with the oil supply system, and if there is no oil, continue to check.

4. The ignition system of the vehicle is faulty. Unplug the ignition high-voltage line on the engine, insert the old spark plug or other pen-shaped metal rod into the spark plug cap, put the spark plug body or metal rod body close to the metal part of the engine, start the engine to observe whether there is a high-voltage flashover, and check the ignition system if not.

Car ignition precautions

1. During the driving of the car, you have to pull out the ignition and open the hidden silver key or turn the key to the locked position, because this will lock the steering wheel and lose steering control.

2. The driver should keep the ignition switch key properly to prevent theft.

3. When the vehicle is on fire for some reason, the key should be turned to the closed position to prevent the vehicle from being in a discharged state for a long time and causing an accident.

4. When using the ignition switch key to lock the steering wheel, do not forcibly rotate the steering wheel to avoid twisting the steering wheel and steering machine.

5. Do not start the engine before opening the relevant locking device with the ignition switch, so as not to cause the vehicle to be unable to turn and travel after starting, resulting in an accident.
