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 worker searched for the first defect. 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 damaged, the light relay can be interchangeable 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:

1.The 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.

4.Detection of starting relay: There is a problem with the general relay, and there is no response when hitting the motor. Plug and unplug the relay again to see if it starts normally! Replace the relay or motor short.

5.Detection of the fuse: Open the fuse and observe whether the fuse indicator is normal and whether the fuse is burned. Replace the fuse.

6.Motor detection: mainly listen to whether the sound of the motor is normal. If the carbon brush of the motor is severely worn, it can be temporarily activated by hitting the motor with a hammer. Go back to the repair shop for replacement.

7.Whether the main output line of the computer box is loose: check whether the plug-in of the computer box and its wiring and each sensor is loose. Fastening is recommended.

Three, no air intake.

Cause of failure: Damage to the eccentric wheel and wear of the eccentric shaft, resulting in the intake and exhaust valves cannot be opened and closed.

Troubleshooting: Call a tow truck!

Hello, there are several reasons for this: battery loss, gasoline flow blocked, ignition system not working well, valve glue, exhaust pipe freezing.

The specific cause analysis and solutions are as follows:

1) battery power loss: low temperature in winter and individual electrical equipment will cause the vehicle to be unable to start, especially in winter long-term dry short-distance low-speed use, the battery voltage will be lower than the rated value, start and can not operate normally, if there is a occurrence, please call the service station rescue**, or find the car right, or temporarily on fire, and then must go to the service station to replenish the battery repentance charge;

2) Gasoline flow is blocked: this situation mostly occurs in the morning when the temperature is particularly low, which is caused by the long-term dirt of the fuel pipeline, and when the temperature is particularly low, the water and debris are mixed so that the fuel pipeline is not passable, and the result can not be started, emergency method: put the car in a warm environment, and the car can start after a while; or use the method of cleaning the oil circuit to completely solve it;

3) The ignition system is not in good working condition: especially in cold weather, due to the low intake temperature, the fuel is not well atomized in the cylinder, if the ignition energy is insufficient, the result will be flooded, that is, too much fuel accumulates in the cylinder, exceeds the fire limit concentration and can not land, emergency method: you can unscrew out the spark plug to wipe off the oil stain between the electrodes, and you can get on the car after installation;

4) Valve gelatinization: winter car, especially after the use of unclean gasoline, the gum in the gasoline will not be burned in the intake, exhaust valve and near the combustion chamber, in the cold morning will cause hard starting, or even not fire, emergency method: you can drop some oil into the combustion chamber with the eggplant hole, generally can start;

5) exhaust pipe freezing: the appearance of the characteristics of the fog cylinder pressure, oil supply and power supply normal, do not hit the car, this situation is easy to occur in the use of particularly low frequency of vehicles, the engine after combustion of the water vapor in the exhaust pipe of the muffler frozen, for a long time, affect the exhaust, serious can not start, solution: put the car in a warm environment, ice can be started naturally.

Hello dear, the following answers have been made to your questions, and I have helped you sort it out! That's it, dear!

When the vehicle does not ignite and has a clicking sound. This condition is generally caused by the following reasons:

The first way is to confirm whether the battery voltage is too low, you can turn on the headlights and some electrical equipment, and confirm whether there is a change in the brightness and darkness of the instrument and indoor lighting during the start-up process. Because the current consumed at the moment of starting is very large, when the old bottle of the slag electric shed is insufficient, it is unable to drive the engine to reach the starting speed and cannot land, and the chain of the magnetic bag and the starting relay is repeatedly sucked together, resulting in a clatter sound.

The second is that there is too much carbon deposition in the intake pipe, too much carbon deposition in the throttle and idle motor, so that the high slag of the engine can not reach the air-fuel ratio of the required beam, resulting in the vehicle can not start, can not talk about the car, and the repeated suction of the magnetic bag and the starting relay produces a clattering sound.

The third type of fuel supply in the mountain fuel system is insufficient, which is basically the same as the factor of excessive carbon deposition in the incoming poor trachea, and it is also unable to achieve the mixture air-fuel ratio required by the engine, resulting in the failure of the vehicle to start.

Fourth, the starting motor or related circuit fault, the magnetic coil can not maintain the suction state, can not provide the starting torque, so it will cause the engine to fail to start, and the bird is clattering and clicking.

The fifth dry macro ignition system failure, this will directly cause the engine to fail to start, if the key door has not been in the starting gear, the starting relay is good round and repeatedly engaged, there will also be a clicking sound.

Questions. <>

<> can't hit the fire.

There was a clattering sound.

What is the reason.

The first way is to confirm whether the battery voltage is too low, you can turn on the headlights and some electrical equipment, and confirm whether there is a change in the brightness and darkness of the instrument and indoor lighting during the start-up process. Because the current consumed at the moment of starting is very large, when the old bottle of the slag electric shed is insufficient, it is unable to drive the engine to reach the starting speed and cannot land, and the chain of the magnetic bag and the starting relay is repeatedly sucked together, resulting in a clatter sound.

The second is that there is too much carbon deposition in the intake pipe, too much carbon deposition in the throttle and idle motor, so that the high slag of the engine can not reach the air-fuel ratio of the required beam, resulting in the vehicle can not start, can not talk about the car, and the repeated suction of the magnetic bag and the starting relay produces a clattering sound.

The reasons why the car will not start are generally as follows:

The battery is faulty and cannot store power. If only the sound of the starter can be heard when starting the car, then it is likely that the battery is losing power and cannot be started.

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

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.

The vehicle's fuel supply system failed. Unplug the oil pipe joint on the upper flush bend of the engine, turn on the ignition switch, and when the instrument light is on (the starter is not running), observe whether there is any pin stuffy oil flowing out. If there is oil outflow, there is no problem with the oil supply system, and if there is no oil, continue to check.

This may be due to engine ignition, which may be overheating or there is a problem with the spark plug, it is recommended to check the ignition coil and spark plug.

The battery hangs, it will cause a series of faults to pop up, find a car to take the power or replace the battery to start the car, if there is a fault code, you need to go to the 4S shop with a special computer to test the cause of the fault and crack the filial piety to eliminate!

The reason why the starter can't start when it clicks:

Battery power shortage, check the cause of battery power shortage: belt slack, generator failure, controller failure, charging line failure, battery maintenance or aging needs to be replaced;

Motor failure: the motor starting gear is seriously worn and needs to be replaced; The starting connection metal block in the motor control mechanism is seriously oxidized, resulting in poor starting contact, and the starting connection metal block can be replaced by removing and grinding the oxide layer.

Care recommendations. The starter is a valuable part of the car and will not be damaged easily, but in order to prolong the life of the starter, proper use is also necessary.

In the process of starting the engine, the starter should introduce 300 400 as (ampere) of power from the battery, so in order to prevent the battery from overcurrent or damage, the starting time should not exceed 5 s; In winter, it is easy to have difficulty starting, and the starting time should not be too long for each time when starting multiple times, and there should be an appropriate interval in each start.

The starter makes a clattering sound, and the start may not be due to: battery lack of power, belt relaxation, generator failure, controller failure, charging line failure, battery maintenance or aging needs to be replaced, motor failure, motor starting gear wear is serious and needs to be replaced, and the starting connection metal block in the motor control mechanism is seriously oxidized, resulting in poor starting contact.

1) According to the working principle, the starter is divided into direct current starter, gasoline starter, compressed air starter, etc. Most of the internal combustion engines are DC-electric starters, which are characterized by their compact structure, simple operation and easy maintenance. The gasoline starter is a small gasoline engine with a clutch and transmission mechanism, which is powerful and less affected by temperature, can start a large internal combustion engine, and is suitable for alpine regions.

There are two types of compressed air starters, one is to drive the compressed air into the cylinder in the working order, and the other is to use an air motor to drive the flywheel. The purpose of compressed air starters is close to that of gasoline starters, and they are usually used to start large internal combustion engines. The DC starter is composed of a DC series motor, a control mechanism and a clutch mechanism.

It is designed to start the engine and requires a lot of torque, so the amount of current to pass through is high, reaching several hundred amperes. The torque of the DC motor is large at low speed, and the torque gradually decreases when the speed is high, which is very suitable for starter. The starter adopts a DC series motor, and the rotor and stator parts are wound with relatively thick rectangular cross-section copper wire; The driving mechanism adopts a reduction gear structure; The control mechanism adopts electromagnetic magnetic suction mode.

2) The starter often has faults and phenomena that cannot rotate or rotate slowly, and in this case, it should be checked from the following aspects:

The battery has no electricity or weak power, so there is a fault that the starter does not turn or rotates slowly.

The starter wire is loose or falls off, and the switch or adsorption switch fails.

The brushes are worn or the brush surface is not correct, and the spring is weak, so that the rectifier is not in good contact.

Short and open circuits of the excitation coil or armature coil.

The rectifier is fouled and the mica sheet is protruding, resulting in poor contact between the brushes and the rectifier.
