What is the reason why the car does not catch fire when it is ignited?

1. See if it is caused by hanging the wrong gear. Some people do not hang the gear in P gear when they stop and turn off the engine, but hang it directly in D gear. Because, if you hang the gear in D gear or R gear, there is no way to start the fire, and you can only start the fire if you hang the gear in P gear or N gear.

Therefore, when he wanted to start the fire again, he could not light it.

2. See if the car is out of gas. In addition to the battery running out of power, the fire cannot be ignited, and the car cannot be ignited when the gas is out. Usually this situation is because the engine is not turned off when you get out of the car, so that the fuel consumption is dried up and the electricity is used up, so the car has no way to ignite the fire.

3. Is there a fault in the gasoline pump? This reason is also somewhat similar to the running out of gasoline. If the starter can run normally when the ignition is ignited, but the car is not on, you need to check the gasoline line to see if there is a problem with the gasoline pump.

4. See if the starter is faulty. If the starter fails, this problem is very similar to the battery running out of power, and it will also cause the fire to not ignite.

5. Is there too much carbon deposited in the throttle place? If there is too much carbon deposited in the throttle, it will also not catch fire. In this case, just step on the accelerator a little bit to ignite the fire.

6. See if the crankshaft position sensor is faulty. There was damage here, and when the ignition was fired, the engine's computer had no way to receive the signal, and there was no way to control the spark plug for ignition. Hope it helps, hopefully.

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 sound of the rattle is the starting motor, which proves that the starting motor is not faulty. There is a clattering sound but it can't be hit, maybe it's the spark plug, or the reason why the oil is not on **.

Some car owners reacted that their vehicles could not start, but there was a clicking sound when starting the vehicle, and such a sound was the sound of the starter driving the engine to run, but the engine could not start.

Solution. 1. Insert the key and twist it until the ACC stops, wait for about 2-3 seconds, let the main power relay contacts be firmly contacted, and let the first part of the device that needs to be energized energized;

2. Continue to turn the key to on, stop waiting for 6-10 seconds, let the oil pump relay engage, wait for the adjustment status of each sensor to complete (self-test), and then turn the key to start to return to ON after continuous operation of the starting plate;

3. Under the guidance of ECU, the optimal position and optimal parameters are automatically adjusted, and finally the engine is successfully started;

4. However, for a short period of time after parking, you can stop without pausing, just observe the water temperature gauge on the dashboard to display the temperature reading, and you can start quickly. When the key is turned to the ignition position, the steering wheel clicks, which is the sound of starting the self-test, which is normal.

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

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 vehicle's fuel supply system failed. Unplug the oil pipe joint on the engine, turn on the ignition switch, and observe whether there is oil flowing out when the instrument light is on (the starter is not running). 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 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.

When the car starts, there is a clattering sound, but it does not ignite, this is because the battery loses power, resulting in the starting motor does not have enough torque to start the engine, you can start with the help of an external power supply, if the battery is used for more than four years, you need to replace the battery.

It is powerless to drive the rotation of the flywheel and cause the car to be unable to hit 2, the car can not catch fire, the clatter may be due to the lack of battery power, the headlights forget to turn off when parking, and there are too many external electrical appliances.

1. When starting the car, hang the gear on the P gear; 2. Unlock the locked steering wheel, lock the steering wheel in the direction a little more and then twist the key to release it; 3. Turn off the power supply in the car when parking, and if you do not turn off the power supply in the car in time, the battery will lose power, and the battery will not catch fire after the battery is lost.

If it can't start, it may be that there is a problem with the starter and the starter needs to be maintained. If the problem is irreversible, it needs to be replaced with a new starter or accessories.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

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 loss of battery power.

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 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 be started 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.

Car Ignition Precautions:

1. When getting on the car to ignite, insert the key and do not ignite immediately, which will have a certain impact on the vehicle battery and starter, so that the car has no time to prepare, and it is not good for the vehicle's starting system.

2. If it is a vehicle with a key to start, do not step on the brake when ignition, after pressing the start button, it is equivalent to the key screwed to the ON position, and then wait a few seconds, and then press the brake to start the vehicle.

3. When starting the vehicle, after the car key is screwed to the start position, do not let go for more than 3 seconds, it is easy to damage the starting device.

5. Do not drive immediately after starting, which will increase the wear and tear of the vehicle.

1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it.

2. Emergency power supply: This is a new type of power bank like a thing, there are two kinds of lead-acid and polymer lithium battery, which can help the vehicle with a loss of power to start, and can also have lighting, charging mobile phones and multi-functional supplies used with an inflatable pump to inflate the car. And it is generally portable, very lightweight, if you have it, you don't have to ask others for help.

Be sure to charge it in time after use and keep it full of power to deal with emergencies.

3. Positive, first connect the positive: first turn off all the electrical equipment on the car, make the key in the OFF position, open the cabin cover to find the battery, there are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one, open the battery cover, pinch the clamp on the head to clamp firmly the positive pole of the battery of the electric car, and the clamp at the other end to clamp the positive pole of the battery of the rescue vehicle. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.

4. Negative connection, negative connection: After the red positive electrode is connected, take out another wire, first clamp the negative pole of the tram battery, the negative electrode is generally black "—" number, and then pinch the other end of the clip, from beginning to end the clip do not touch other places, to clamp the negative pole of the rescue vehicle battery, when the connection will pop out of the electric spark, please don't be afraid, this also shows that you are right. The reason why the negative electrode is not connected first is because the whole vehicle is basically a negative electrode (that is, commonly known as "tie iron"), if the negative electrode is connected first, when connecting the positive electrode, the clip will cause a short circuit and burn the parts on the car when it touches any conductive place in the body.

5. After starting the vehicle, first remove the negative, and then dismantle the positive: after the battery is connected, the rescue vehicle will first ignite and charge the battery, and then the no tram enters the vehicle to open the key, at this time the instrument light will be lit smoothly, and then try to ignite (not more than 5 seconds), if it fails to start smoothly, step on the accelerator of the rescue vehicle, and the speed is kept at about 2500 rpm, and then the tram is ignited again, if the starter is no problem, the car has oil in the case of general can be started smoothly, after the non-electric vehicle starts, Remove the negative clamp first, then remove the positive clamp, for the same reason as why the negative pole is followed by the fourth one.

The positive and negative poles of the battery must not be reversed, and the order of assembly and disassembly should be strictly in accordance with the order of first connecting the positive and then the negative, and the first dismantling and then the positive.

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.

Hello! The car battery is out of power or the car is out of gas are common reasons why it can't catch fire, especially if the battery is out of power, it may be that you forgot to turn off the car power when you got out of the car, and the car power supply belongs to the state of being turned on, and the power is consumed!

It may be that the battery is out of power, first check whether the line of the battery is plugged in normally, if it is normal, it means that the battery is out of power, and it is good after charging.

If the battery is fine, then it may be a problem with the spark plug, just replace the spark plug.

Reason: The start of the engine is completed by the current of the battery to push the spark plug ignition, resulting in the sudden point of the engine may have the following two reasons, the first is likely to be caused by the battery rust or battery dripping, and the second is caused by the dampness of the engine spark plug on rainy days.

Maintenance method: Check whether the battery liquid in the battery is sufficient every two months. If the liquid level is between the upper and lower lines, it is considered appropriate.

At the same time, the liquid level difference of each tank should be checked. If the liquid level is insufficient, you can unscrew the lid on the battery and pour distilled water to make up the liquid level. Then check the terminal blocks of the battery and use an iron brush to remove dirt from the terminals.

If the clamp is badly defiled, you can use sandpaper to rub it along the inner wall to rub off the dirt. If the spark plug is wet, take it out and bake it with a lighter so that the moisture on it can be steamed as quickly as possible.
