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

The most annoying thing when driving is that the car can't catch fire, especially when you have something urgent to go out, or if you can't catch fire when you are stranded on the road, it can really kill people in a hurry. So why is this happening, and how can it be avoided?

There are several main reasons why the car does not catch fire:

In the first case, the car battery is dead. Once because the child was naughty, the car lights were on overnight and no one found out, the next day the car could not catch fire, charged a whole day of electricity to catch fire, this situation can be found to take the wire to charge, you can also find the car charging treasure to charge, the car battery will not only fail when the power is exhausted, but also will not ignite when the service life is too long, the service life of the general car battery is two to five years, pay attention to inspection and replacement.

In the second case, the ignition device is malfunctioning. Starter failure or starter circuit failure. Engine failure or spark plug failure, engine management system failure and poor line contact will lead to no fire, at this time, stop one by one to check the fault, the line is more complicated, if necessary, tow to the 4S shop for maintenance.

In the third case, the car runs out of gas. When the car is low on gasoline, there will be a red light flashing to remind the owner that it is time to refuel, when the gasoline is not enough to maintain the car running, it will naturally not ignite, and the gasoline should be replenished in time. And if the quality of gasoline is not good, there will be no ignition, so you should choose the best gasoline and choose a reliable gas station.

Fourth, there is too much carbon deposit. When the engine is working, carbon deposits will be generated, and when the carbon deposits are so much that they block the air outlet, they will not ignite, and it is said that if you do not step on the accelerator and do not ignite, you can ignite when you step on the accelerator, which means that it is the carbon deposit of the throttle, so it is necessary to pay attention to cleaning up in time, and it is said that running at high speed can reduce carbon deposits.

In the fifth case, the gear is not right. This is mainly for manual transmission of the car, many people after stepping on the brakes always do not return to neutral gear directly to turn off, the next time to start, do not check the poor gear directly ignition, naturally can not hit. It is important to remember that the car can only be ignited when it is in neutral, put the gear in neutral before turning it off, and check the gear before driving the next time.

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.

1) Causes of oil supply system: low-pressure oil circuit blockage, loose pipeline oil leakage, high-pressure oil pipe with air, poor technical condition of fuel injector, incorrect fuel injection timing angle.

2) Causes of starting device: power failure, poor contact of electromagnetic switch, poor contact between the commutator of the starting motor and brushes, and slippage of the clutch of the transmission mechanism of the starter.

3) Insufficient cylinder compression pressure: the cylinder gasket is damaged and leaks, the valve is not closed tightly, and the piston cylinder liner is worn and leaking.

4) Insufficient air intake: The air filter element is blocked.

At this time, we must need rescue to help you deal with it, and you must not mess with the car casually, otherwise it will damage our engine.

1. Take out your phone.

2. Call a trailer.

3. Maintenance. 4. OK.

Look at your description should be a battery problem, teach you a way to use the cigarette lighter charging head with voltage detection function to detect the voltage before ignition to know whether it is a battery problem, I think the battery problem is very likely.

The solution to the car that can't start and can't catch fire is as follows:

The first type: out of gas. We went out to rescue a car before, and the fuel gauge showed that it was below the red line, so naturally it could not catch fire.

The second type: 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 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.

The third type: 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.

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.

The quality of gasoline is poor and substandard;

Oxygen sensor failure;

Faulty air flow sensor;

Carbon build-up in spark plugs or engine knocking.

The quick fix for the car not catching fire is as follows:1. The steering wheel is locked. Today's cars are very smart, almost all have anti-theft functions, and the steering wheel will be locked when the car is not used for hailstorm, and the car will not catch fire at this time.

In this case, you only need to gently turn the steering wheel while twisting the key to successfully ignite.

2. When the oil volume of the car is not enough or the battery is out of power, it will suddenly fail to ignite. The fuel level is not enough to solve the problem, you only need to refuel the car to start successfully. However, the battery power loss still needs two small tricks to verify.

The first way is to press the horn, if the sound of the horn is relatively small, it is a loss of power. The second way is to turn on the ignition to start the car, but do not step on the brakes, if the light of the headlights is weak, it means that there is also a loss of power. In the case of power loss, go to the repair shop in time to repair and replace the battery with a new one.

3. When the car is ignited, it must be hung in the correct gear, and it cannot be ignited if it is wrong. The correct gear should be P gear or N gear, and the owner of the source spine should check whether he is in the wrong gear when ignition. If you can't ignite due to a wrong hanging, you can restart it by adjusting it.

1. Check the battery level.

The biggest possibility that the car does not catch fire is that the battery is insufficient, at this time, turn the key only to hear the sound of the clang, you can try to refuel the car and then ignition, if it really doesn't work, you can only replace the battery or charge the battery in time.

2. Check whether the flow of oil is blocked.

If you are driving in winter, the viscosity of the oil will increase, and it will be difficult to flow, which will increase the resistance of the engine of our vehicle.

3. Check whether the spark plug is faulty.

If the spark plug is not replaced in time, the vehicle will have a sense of frustration, and there will be shaking when idling, we can disassemble the car body to check the spark plug to see if there is any air leakage, if there is, to replace it in time.

4. Check whether the exhaust pipe is frozen.

If it is an electronic throttle, it is easy to accumulate carbon, and the water vapor produced by the engine operation will freeze. Therefore, we must run more long distances to prevent carbon accumulation, and we can also drain the stagnant water in the exhaust pipe.

5. Check the condition of antifreeze.

If it is a cold winter, we must not add some good antifreeze to the car, do not add water or bad antifreeze, otherwise it is easy to freeze the entire waterway, if it is serious, it may also freeze the engine, so that the car can not catch fire.

6. Check whether the motor is faulty.

If the loss is a problem with the car oil pump, the gasoline pressure will be insufficient, and there will be no ignition, motor failure, gasoline grid blockage will lead to the situation that it cannot be ignited, so be sure to clean the oil circuit in time and replace the gasoline grid.

7. Check whether the parking position is a problem. Sails included.

If the vehicle is parked in low temperature conditions, if the engine is started at this time, it will be relatively difficult, the engine will wear out quickly, and the service life will be affected, so if it is not parked properly, it will also lead to no fire, it is recommended to choose some flat and warm places to park.

1. The ignition is difficult due to carbon deposition in the car, and the throttle can be cleaned, the carbon deposition in the intake tract can be cleaned, and the fuel injector can be cleaned;

2. If the engine cannot ignite due to insufficient low pressure in the fuel circuit, check the fuel pressure regulator, gasoline pump, gasoline filter element and pipeline;

3. If the car battery is insufficient or the amount of oil is insufficient, you can ask for help from the surrounding car owners according to your own conditions, and apply for emergency measures such as taking electricity, borrowing oil, and trailering.

4. The steering wheel is locked and cannot be started, so you only need to screw the key while shaking the steering wheel;

5. Check the gear of the car, P gear or N gear is the correct gear, and the gear is placed in R gear or other gears, which will cause no ignition, and the correct gear should be adjusted.

Reasons why the car won't catch fire:

1. The car battery is insufficient or the remaining oil is not enough, which is also the most very easy to check item, and it is also the most likely to cause the car to not catch fire. The remaining oil is very easy to distinguish, the ignition key is turned to the ON gear, one key to start the car system without stepping on the brakes, press the running function key a few times, turn on the headlights, and the light effect is significantly weakened by the strong or directly not lit. Then press the speaker speaker, the sound of the speaker is significantly weaker than usual, or it is not loud, then it can be judged that the battery is insufficient.

2. The steering wheel is locked and cannot be started, which is also an ordinary anti-theft function that many cars have.

3. Check the gear of the car, under normal circumstances, P gear or N gear is the appropriate gear for the operation of the automatic transmission car.
