The car doesn t catch fire, and all the gauges don t light up?

There are two possible scenarios for failure to ignite: low-voltage circuit failure and high-voltage circuit failure.

1) Common faults in low-voltage circuits: insufficient storage of power in the storage BAI battery; Poor or deranged wire connections; Poor battery tie-up; Damage to the distributor or Hall sensor; Damaged ignition switch or poor wiring; The transistor ignition control unit is damaged or poorly wired. Most of the diagnostic methods for low-voltage circuit faults use ammeter or voltmeter to check the fault line by line to eliminate the fault point.

2) Common faults of high-voltage circuits: high-voltage lines fall off or leakage; Breakage and breakdown of distributor cover; Ablation, rupture, breakdown of distributor fire head; The spark plug electrode gap is too large or too small; Excessive carbon deposits in the spark plug; The spark plug insulator is damaged.

The ignition coil is damaged or the wiring is falling off. Most of the faults of high-voltage circuits adopt the high-voltage fire test method, that is, the high-voltage line in the center of the distributor or the high-voltage line of a cylinder is unplugged, and the wire head is placed at a distance of 3-6mm from the cylinder block, and the engine is started to test the fire. If there is a spark and the spark is strong, it means that the ignition system is working properly.

Extended Information: How to maintain your car:

1. Inspection of spark plugs.

Normal spark plug insulating ceramics are intact. There is no rupture leakage, and the spark is blue and strong. If an abnormality is found, the gap should be adjusted or the spark plug replaced.

Check the gasoline filter, if the oil supply is not smooth, check whether the gasoline filter is blocked, if the foreign body is blocked, it should be replaced in time.

2. Maintenance and inspection of batteries.

Check whether the battery is firmly fixed, the electrolyte should be between the upper and lower limits, and the electrolyte or distilled water should be added to the high line in time when it is close to the lower line. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry.

Vehicles that have been placed for a long time should take off the positive and negative cables of the battery, rewire and start the engine about 20 minutes after about half a month, and charge it in time if the power is obviously insufficient.

The car can't catch fire, all the instruments, it's not lit, there should be some problems with the line. Find out the fault of the line well and you can hope to recover.

Check the head of the battery, if necessary, remove it, corrode the abrasive cloth, add butter, and install it back, not enough to start and call a friend to drive to take it, and rescue the small problem.

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 ignite, the dashboard light is fully lit, the battery is not enough or the engine failure is caused, this kind of problem needs to go to the 4S shop to use professional instrument maintenance. Battery power is a relatively common phenomenon, if the instrument light is on, it means that the battery still has power, but not enough power to start the engine. If it is helpful to you, I hope you can adopt it, thank you.

Answer: Pro, hello, I am happy to answer for you It may be a problem with the line, which is generally caused by a short circuit or a bad joint in some places, and needs to be repaired in a repair shop. It may be caused by the battery running out, and it can be solved by charging, for example, taking the battery off and charging it with a charger.

1. The problem of the battery. For example, the battery life reaches the limit, or the battery pile head is loose, the contact is not good, and the pile head may be oxidized.

2. The starting fuse is broken.

3. If all the indicators of the dashboard are not lit and the engine is turned off in time after starting, it is likely that there is a problem with the dashboard, and the common reason is that the instrument CPU is damaged.

You can press the horn first to see if the horn is ringing. If the horn is loud, the battery is fine; If the horn does not sound or the sound is very small, it means that the battery is out of power. In the case, if there is basically no sound at all when the key is running, it is basically certain that the battery has run out of electricity.

Since you can't see the real car, you can't make an accurate judgment on the fault, so it is recommended to immediately contact the 4S store and ask for professional help.

If the car instrument does not light up and does not catch fire, it is likely that the battery is dead or short-circuited, which may be due to the failure of the battery itself or the battery is exhausted due to the unturned electrical equipment in the car. It can also be caused by insufficient fuel pressure, incorrect throttle position sensor signal, poor fuel pump or poor spark plug operation. In addition to the cause of improper human operation, there may be motor failure, oil pump supply, fuel injector problem, sensor failure, etc.

Hello. In the case of such failures, it is necessary to analyze them on a case-by-case basis. The first thing that needs to be checked is the battery voltage.

If the battery is out of power, the vehicle will definitely not start. It's also possible that there is a problem with the dashboard's insurance. It is recommended to go to a professional repair shop or four-S shop for further inspection and maintenance.

Please check the battery voltage, it may be caused by leakage. Also, check whether the battery terminal is loose.

That is, there is no power, and the battery needs to be replaced.

The battery is dead, find an ignition battery to try.

You have to find a professional to test this to know...

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.Spark plug blockage If the vehicle starts successfully, but there is obvious frustration when starting, then we should observe the operation of the engine, there is continuous shaking 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 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.

Is it the trunk, the cab shed light is on, there is no fire and there is a sound that the battery is insufficient, if the light is not turned on, then the battery needs to be replaced. Possible reasons are: insufficient fuel pressure, incorrect throttle position sensor signal, poor working fuel pump, poor working spark plug.

The car does not catch fire, and the dashboard shows that there are basically fault problems.

1. Detect the state of the battery, and most of the difficulties in starting the car in winter are caused by the battery loss or the expiration of the battery period. 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 ignited. Do not ignite continuously to avoid running out of battery.

2. Change the appropriate engine oil, in winter, as the temperature drops, the viscosity of the engine oil will increase accordingly, and the engine oil flow will be difficult, so the engine resistance will increase. If it is difficult to start, please check whether the engine oil is not labeled correctly.

3. Replace the spark plug immediately, the spark plug is easy to cause carbon deposition, leakage, excessive gap, ablation and other problems after a few years of use, which will cause difficulties in car ignition, cold start, and even heat engine start are basically very difficult, and multiple ignitions are often required. If you drive to a certain mileage or feel that the vehicle is difficult to start, weak to drive, shivering and vibrating, increasing fuel consumption, or inexplicably stalling, please check the spark plug status and replace it immediately.

If the battery is out of power, you can call the insurance company for rescue, and you can find other car owners to start it.

If the instrument indicator is not lit, first check the power supply fuse of the dashboard, and replace it if it is blown. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there is an open circuit or short circuit, which will also cause the car dashboard to not light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

If all the dashboards don't light up, it's likely that the battery is out of power. In this case, it is impossible to ignite.

It should be that the throttle is dirty, or it may be that the battery power (current) is insufficient. 1. Explanation of valve joint: throttle is a controllable valve that controls air to enter the engine, and there are two kinds of traditional cable and electronic throttle.

When the car meter does not light up, it is likely that the battery is dead or short-circuited, it may be that the battery itself is faulty, or it may be that the electrical equipment in the car is not turned off and the battery is exhausted. This can also be caused by insufficient fuel pressure, incorrect throttle position sensor signals, faulty fuel pumps, or faulty spark plugs. In addition to the reasons for improper human operation, there is also the possibility of motor failure.

When the car instrument does not light up, it is likely that the battery is dead or short-circuited, it may be the fault of the battery itself, or it may be that the electrical equipment on the car is not turned off and the battery is exhausted.

This can also be caused by insufficient fuel pressure, incorrect throttle position sensor signals, faulty fuel pumps, or faulty spark plugs. In addition to the reasons for improper human operation, there may also be motor failure, oil pump supply, fuel injector, sensor failure, etc. These complex situations need to be handled by professionals.

However, you can avoid these complicated situations by paying more attention to the following things when using a car.

The first is the issue of oil. After unpacking, it was found that there was water and mud in the tank. With such oil, it is impossible for the car not to be damaged. Therefore, it is better to remind car owners to go to a regular gas station to refuel. When going out, they can bring a gauze bag around the muzzle of the refueling gun to filter out impurities.

Second, no antifreeze is added. Some car owners add water or low-quality antifreeze to their cars. As a result, when the winter was particularly cold, the entire waterway froze and the engines cracked.

In this way, the car water pump does not work, it does not catch fire, and the other parts of the engine are harmed.

What is the reason for the yellow light of the car instrument engine.

The reason why the instrument engine lights up yellow is that the engine is in a bad combustion state, air intake problems, bad oil, sensor failure, etc. When this happens, the owner should go to the local 4S store as soon as possible, read the fault through the program and the driving computer, find out the relevant cause and take countermeasures.

Engine fault light, as long as the fault light is on, it means that there is a problem in a certain part of the car. But if the car is still moving, it is a particularly big problem that it does not fight. In the event of a particularly severe malfunction, the red light will be illuminated, while the engine fault light will be yellow.

After the fault light is on, try not to travel long distances, and drive to the nearby repair station as soon as possible to check and repair to avoid temporary small faults from developing into major problems.

When the engine fault light is on, the car does have some abnormal phenomena, such as violent shaking and weak acceleration. In this case, it is better not to continue driving. You should pull over and ask for a rescue trailer.

If it's close to a repair shop, you can force a car. The presence of obvious fault phenomena indicates the presence of a serious fault. If you continue to drive forcibly, the breakdown will increase, or the damage caused by the breakdown will gradually accumulate and develop into another type of breakdown, and it is not recommended to continue driving.
