Causes and solutions for cars not catching fire?

Check the battery power loss.

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.

The gear is not in the P gear when starting.

Friends who drive manual transmission cars should not have this kind of problem, and under normal circumstances, they stop and take off the gear and pull the handbrake to turn off the ignition in one go. Friends who drive automatic transmission may forget to hang the P gear or hang on the N gear when parking because the automatic transmission does not need to often manipulate the gear handle, and when they get up again, they don't notice it and ignition directly, and the result is that the car can't catch fire.

Solution: Hang to the P gear and light it again, this situation is completely caused by their own negligence, driving is also a meticulous job, everyone should focus on trying not to make this kind of mistake.

The smart key is out of power.

This question is only for those car owners who have a one-button 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 your car happens to start without a key, then you can try to stick the key on the start button and press the start button, if it still doesn't work, then you can only choose to change the battery of the smart key first.

Whether the steering wheel is locked.

When you stop the car and turn off the steering wheel, the steering wheel will automatically lock when it does not return to the center and reach a certain angle, and when you come back to get started, you will find that the steering wheel does not move, the key door cannot be screwed, and the car will naturally not catch fire.

Solution: Don't worry, this is actually an anti-theft system, as long as you put the steering wheel in the direction of the lock a little more and unscrew the key door, so that the lock can be unlocked, and the engine can be started naturally.

There is no gasoline or no fuel lines.

There is no oil pressure in the engine supply line. This situation usually occurs in the morning when the temperature is very low, and is caused by long-term dirt in the fuel line. When the temperature is very low, the water mixes with debris and the fuel line is blocked, and as a result, it cannot be started.

There are many reasons why the car cannot ignite, it may be that the ignition equipment is faulty, or the battery itself is insufficient, or it may be caused by the lack of gasoline in the car, so it is necessary to inspect and repair the car according to the actual situation, and replace the bad parts in time, so that it can be ignited more smoothly and drive safer.

There are several common reasons why a car won't catch fire:

a. The battery is dead. This situation is easy to check, press the horn to know. Due to long-term use or the expiration of the battery life, it is generally recommended to replace the battery in time after two years.

b. Spark plugs. The spark plug is a key component in the automobile ignition system, and the ignition system of the vehicle is the key to whether the heart of the car is working, so whether the spark plug can work normally is directly related to the working performance and efficiency of the vehicle. Workaround:

Check the ignition system and rule it out one by one.

c. Excessive carbon deposition will also lead to difficulty in igniting the vehicle or not igniting, solution: cleaning, often running at high speed can also reduce carbon deposition.

Insufficient battery power or fuel level of the car, the steering wheel is locked and cannot be started, the car gear is wrong, circuit or electronic faults, and oil circuit faults may be the reasons why the car cannot ignite. If the above conditions are checked and ruled out, but the vehicle still does not ignite, then the turning sound of the starter can be heard, but the engine cannot start; The other is that after twisting the key, there are no two expressions of any sound to judge.

If the car does not catch fire, it is generally a problem of the oil circuit or circuit, first check whether the car battery is electric, and then check whether the activator plug has too much carbon. Also check if your oil circuit is not smooth, or if the oil supply is insufficient.

The reason why the car can't catch fire is, of course, the circuit problem, if there is a problem with the circuit, the way to solve the problem is to repair the circuit.

The reason and solution for the car not to catch fire is generally that the battery of the car is out of power, and in this case, the car battery can be replaced as soon as possible.

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.

The steering wheel is locked. When the owner does not turn the steering wheel back to the right after parking and turning off the ignition, it is easy to lock the steering wheel, this function is mainly for anti-theft considerations, and the result is that the key can not be screwed and cannot be ignited.

2.Low on fuel. Generally, this situation mainly appears in the process of driving, if the engine suddenly turns off during driving, you should look at the fuel gauge as soon as possible, confirm whether the fuel tank has no oil, at this time as long as you refuel the car.

3.The battery is running out of power.

There are two possibilities.

1.The battery loses power, resulting in insufficient power to provide power to the starter motor.

2.The starting motor is stuck, the battery storage is sufficient, and the starting motor relay squeaks.

Causes and solutions for cars not catching fire? We judge it this way. If you can't judge it, we may judge it like this, and if you can't judge it, it may be that the oil circuit is blocked, and you must go to the regular killing chain to check, because this is a safe event.

There are many reasons why it is difficult to start, and it must be checked to be determined, and I am really helping you look forward to it

The reason why the car does not catch fire is caused by improper operation, such as no fuel, no electricity, wrong gear, and these situations are quite common, observe the fuel tank situation in time, and the dashboard prompts that the fuel volume is insufficient, and refuel nearby; If the car battery is out of power, you can use someone else's car to connect the battery to ignite; Operate the gears correctly in accordance with the car instructions.

What should I do if the car does not catch fire?

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

Reasons why the car won't catch fire:

1. If there is no oil, the oil gauge shows that it is below the red line, so it will naturally not catch fire;

2. If 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, and it is generally recommended to replace the battery in time after 2 years; In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failure;

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

There may be several reasons why the car cannot ignite, and the steering wheel is in a locked state: when the steering wheel is not corrected when parking, it is easy to have the steering wheel locked, resulting in the key being inserted and not being able to screw, and the car can not be lit. 2

The battery of the car has a power loss: the battery of the car is also a consumable, and it is recommended to replace the battery once in 2-3 years. If the battery is out of power and cannot ignite, you can take the method of taking electricity, first of all, the front of the two cars "face to face" (the two cars can be as close to each other as possible), and then turn off the rescue vehicle, so as not to burn the battery line due to excessive current, the electrical switches of the rescue vehicle are turned off, open the engine compartment of both sides (some car batteries are placed in the rear trunk, such as BMW), and find the positive and negative poles of the batteries on both sides (with red "+" for the positive pole and black "-" for the negative pole).

Remember the positive and negative poles of the vehicle, don't make the wrong connection.

Next, how to correctly connect the wiring method is: first connect the positive end of the battery of the loss-stricken vehicle with the positive end of the rescue vehicle battery; Then connect the negative pole of the rescue vehicle battery to the wire and then connect it with the iron sheet of the body of the vehicle with power loss (try not to connect the negative electrode, it is easy to produce sparks, and it will cause damage to the battery in serious cases.

Black is the negative wire, and red is the positive wire.

After making sure that the wires are connected correctly and that the contact is good, start the rescue vehicle; Let it run for a few minutes before charging the vehicle with a loss of power. Then start the loss-free vehicle.

If the loss of power vehicle can not start, this is to give the throttle of the rescue vehicle to some oil, and then to start the loss of power vehicle, remember not to force the start, pay attention to the start of the interval, if it can not start, it is necessary to consider whether the wire is too thin, the current caused is not enough.

Remember the positive and negative pole markings on the battery.

When the vehicle is started, the battery clamp can be removed at this time, and the order of taking power should be:

1. First remove the negative pole of the rescued vehicle with the iron wire, and then remove the negative pole wire of the rescue vehicle;

2. Furthermore, remove the positive wire of the rescue vehicle, and then remove the positive wire of the rescued vehicle.

Remember the order of unplugging 4 4

If the motor fails, or the fuel filter surface is clogged and the car doesn't start, it's time to ask a professional to solve it.

1. There is no response when the vehicle starts, so in this case, you first need to check whether it is caused by the battery power loss? If the battery is out of power, you need to charge the battery or replace it with a new one.

In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked? If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. If there is a problem with the anti-theft system, you need to re-do the anti-theft matching.

2. The vehicle engine can rotate, but it does not catch fire, so in this case, it is important to check whether the oil pressure of the gasoline pump is insufficient? Or the vehicle engine does not ignite, if the pump oil pressure is insufficient, this situation requires the gasoline pump to be replaced. Check the fuse or wiring of the gasoline pump.

Reasons and solutions for cars not catching fire:1. It may be that 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.

2. The battery is out of power. 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 it is generally recommended to replace the battery in time after 2 years. In addition, the installation of argon headlights, high-power audio, etc. are also the causes of vehicle circuit failure.

The situation of the vehicle without power is easy to check, just press the horn to know.

3. Spark plugs. Generally, the most is to check the spark plug of the car first, because the spark plug is the key component of the car ignition system, and the ignition system of the vehicle is the key to the heart of the car does not work, so whether the spark plug can work normally is related to the working performance and efficiency of the vehicle. Contingency Method:

The spark plug can be wrung out and wiped clean, and the car can be loaded after reassembly. The thorough approach is to check the ignition system and rule out the causes of low ignition energy, such as spark plug electrode gaps, ignition coil energy, high-voltage line status, etc.

1.The fluidity of the oil deteriorates, and the resistance increases.

The lower the temperature, the greater the viscosity of the oil, the worse the fluidity, and the greater the resistance of the engine. Therefore, in winter, it is advisable to switch to a less viscous oil to cope with cold weather. At present, most of the engine oil on the market uses SAE and other grades to identify the viscosity, and the more the number in front of the "W", the thinner the engine oil, the higher the low-temperature fluidity, and the stronger the cold start ability.

2.The spark plug deadline has arrived.

If the vehicle starts successfully, but there is a noticeable frustration at start, accompanied by increased idle shake and reduced engine acceleration, it is likely to be caused by spark plugs. At this point, you can start with the spark plug to check the combustion color, the gap between the electrodes, and whether there is air leakage between the porcelain and the metal housing. Generally speaking, it is not a problem for a spark plug with excellent quality to run 100,000 kilometers.

3.There are problems with the air intake, fuel injection, and exhaust systems.

Once the throttle imitation bridge door and air intake are dirty, it will not only cost fuel to open, but also the throttle will become sluggish and non-linear, and the car will suddenly rush forward when the throttle is increased. Dirty fuel injectors will lead to increased fuel consumption, idle shaking, and exhaust smell. In terms of exhaust, on the one hand, it is prudent to pay attention to check the three-way catalytic wide celery, and the second aspect is to pay attention to whether there is ice in the exhaust pipe.
