When the car is ignited, there is no sound, what is the reason that it does 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.

Generally, there will be a sound at least the starter when ignition, and if there is no sound, it may be that the battery is losing power or that the iron is bad.

When the car is ignited, there is no sound, indicating that the car is on fire. It can't be operated, which means that there is something wrong with the car. So you should go to the repair shop and fix it.

Indicates that the motor does not rotate. Check the battery voltage. and ignition lines.

It may be that the battery is out of power, or there is a problem with the motor.

The car does not catch fire and there is no sound when it starts, which may be due to the following reasons:

The starter cannot work properly due to the lack of power in the car battery, and the car starting circuit or the start switch is faulty and there is no electricity connected to the starter, and there is a possibility that the starter is broken, so it is best to go to the maintenance plant for specific inspection.

The starter works, but the engine doesn't. This is complicated by the fact that it can be caused by one of several failures.

1) Electrical or electronic faults. The phenomenon that occurs is very sudden and without warning. The faults of the circuit are:

The fuse is blown out, the high-voltage coil is broken, the low-voltage circuit is broken, the center ignition wire is off, the distributor head is leaking, and the spark plug is damaged. Electronic failure mainly refers to the loss of function of the computer control board.

Oil pump failure, oil circuit failure, oil filter blockage, carburetor failure, nozzle damage, etc. Sometimes it happens that the fuel tank is empty and the owner doesn't know about it. Add a few liters of petrol and you'll be able to solve all the problems.

3) Mechanical failure. Common mechanical failures are: time band (chain) breakage, cylinder leakage without pressure, etc.

There is no sound of ignition, first of all, you first see if your battery has electricity, you can try to press the horn to make no sound, the instrument is not bright, if the instrument is bright and the horn is also very loud, then there are many reasons, such as the starter is not good, the line is faulty, the fuse relay is not good, if the instrument is not on, the horn is not sound, that is, the battery is not good and there is no power. At this time, you can call rescue, call 4S** or insurance company**.

There is no reaction to the car ignition and there is no sound.

The first thing to consider is the issue of electricity. If the remote control can unlock and open the door, it means that the battery is charged. And twisting the key (or pressing the start button on the brake) does not respond.

It is possible that the ignition switch is malfunctioning. If you screw the key to the ON position, the dashboard light is on, indicating that the key switch is fine. The point of failure is transferred to the control system and the line.

For example, whether the fuse is blown or not, and whether the starter and suction switch are normal. If the fuse is fine. It is recommended to use a wrench to tap the starter suction switch.

A similar phenomenon can occur when carbon brushes are not in good contact.

Check the battery, is it a long time, the battery is out of power caused by the car has no response, if the light of the dashboard is on, check whether the ignition relay is broken.

The preliminary judgment may be that the battery is out of power, and it is recommended that you find a car after-sales service personnel to help you check and repair it as soon as possible.

The reason why it can't catch fire should be that the battery is out of power, or the positive and negative pole wires connecting the battery pile head are loose.

Hello: first check whether the battery power meets the starting requirements, if the horn does not sound, it is recommended to find the same capacity battery for parallel start.

.First of all, exclude the impact of the battery is not electric or the power is too low, if there is a voltage detection in the car can be read directly, if not, you can turn on the headlights to observe the brightness of the headlights, if the brightness of the headlights is dim or directly not bright, the battery is seriously damaged. You can start it with another car.

If your car is ignited, the slightest sound does it mean that your car battery is no longer charged. At this time, you can find a car to take the battery, and charge the car for a while after charging, it may be where you have a car and there is a leakage.

There was no sound when the car was ignited. Check whether the main switch of the car circuit is energized. It may be that the starter circuit switch is off and not energized.

Connect the circuit switch of the starter. There is also whether the car battery has charge or not. Finally, it could be that the boot is faulty.

Battery and starter failures need to be repaired at an auto repair shop.

When the car is ignited, there is no sound, and it cannot ignite, which is likely to be caused by the exhaustion of the car's battery, it is recommended to check the battery first.

If you can't start the ignition, it's because the car's battery is out of power. You need to use another car to start with the battery, and then let the car stay on and charge. When you get out of the car later, turn off all electrical appliances.

Electrical problems.

First of all, see if the battery is dead, and see if the starter is broken.

Looking for a car repairer, ask here how to tell you.

There will be a situation where the starting voltage is low. Therefore, when winter comes, the battery electrolyte should be replenished in time, or the battery should be replaced with a new one. If the vehicle is not used for a long time, the battery should be removed and placed in a warm place to avoid damage to the battery.

If you feel (listen to the sound) that the starting speed is too low, then it is impossible for the vehicle to start. At this time, the battery voltage should be checked, especially in the winter, after leaving it overnight, the engine will be very difficult to start. After two failed ignitions, the battery runs out of power and the spark plug is prone to drowning.

If possible, the voltage can be measured with a multimeter; If the spark is strong and green, it means that there is no problem, if the spark is weak and red or there is no fire, it means that the battery is out of power. If you run out of gas, everyone will know! In fact, there are really some careless car owners who don't know that their cars are out of gas!

Therefore, when the car does not catch fire, the first thing you should check is to see if there is still gas in the fuel tank of your car.

Generally, do not wait for the fuel indicator light to turn on before refueling, it is best to refuel when the pointer is at a quarter of the fuel gauge, this is to protect the fuel pump. At the same time, we have to go to a regular gas station to refuel, if the oil we add contains too much water, the car is easy to be damaged. You can find the "emergency treasure" to start the power supply, or use the "river dragon" to find other vehicles to start the battery, and then go back to the store to check the original car with no battery after starting.

It is possible that the light is not turned off after the ignition is turned off, the generator is not generating electricity, or the battery needs to be replaced.

When there is neither fire nor oil, the crankshaft signal should be checked, and anti-theft. Because it may be the oil and electricity disconnected by the computer, you can use an oscilloscope to check the crankshaft waveform, and the camshaft waveform. You can use the detector to read whether to go into the anti-theft mode, in short, the diesel engine in winter to determine the number and the weather to adapt to the general -10 can be worry-free, the cold north -35 is not impossible.

The fuel injectors of gasoline and diesel engines can become clogged due to carbon deposits after several years of use, which can also cause ignition difficulties.

It is very likely that there is a loss of power, and if the battery is out of power, there is no way to take a taxi. Of course, it is also possible that there are other reasons, and problems with the ignition system can also be caused.

This is considered to be the reason for the engine, because the engine has been worn, so it will not be able to hit when ignition, or it may be because the wiring inside is broken.

To deal with this kind of problem, we have a point of judgment, that is, pay attention to the engine speed of the dashboard when ignition, if the engine speed is very low, the highest time is also lower than 250 rpm, you can judge that it is a problem with the control of the starter, and the control of the starter is an emergency method when ignition: unscrew out the spark plug by hand, wipe it clean with clean paper, and then install it back in place. To see if it can be started, the thorough way is to check the ignition system and rule out the reasons for low ignition energy, the common ones are, ignition coil energy, high-voltage line status, and spark plug electrode gap.

This fault is mainly oil and electricity. If the Dada sound is very loud, the battery and motor should be normal. Mainly check whether the oil circuit is smooth; Whether there is oil in the carburetor, whether there is carbon deposit in the spark plug, and the clearance adjustment is appropriate, about between.

There is also whether the fire splitter head is normal. Start the cart to avoid crowded road sections, after starting, you should quickly switch to 2nd gear, then release the clutch pedal, step on the accelerator, control the throttle, and avoid stalling.

Once you reach a comparable speed, put the transmission into gear, then quickly release the clutch pedal and refuel. Once the engine starts, you should quickly press the clutch pedal while controlling the throttle so that the engine does not turn off, and then stop slowly. Of course, it takes at least two people to determine the positive (+) and negative (-) poles of the two batteries to start the cart, and use cables to connect the positive and positive electrodes, and the negative and negative electrodes respectively.

It is necessary to pay attention to the positive and negative poles of the battery, and to ensure the reliable connection of the cable. Arrange the direction of the cable to prevent the cable from scratching with the tape or fan when starting.

Insufficient voltage will also cause the car to not catch fire and make a clattering sound. The reason for the insufficient voltage may be because the battery has been in the battery for too long, resulting in aging and less stored power; The car is not turned on to listen to songs or turn on the air conditioner. The ignition should be turned on before the vehicle is pushed, and when it reaches a comparable speed, the transmission should be put into 2nd gear, and then the clutch pedal should be quickly released and refueled.

Once the engine starts, you should quickly press the clutch pedal, control the throttle at the same time, do not let the engine turn off, and then stop slowly.

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.
