    1. When starting, only the "gurgling" sound of the electromagnetic switch of the starter is heard, or the starter drives the crankshaft to rotate slowly a few times when starting for the first time, and then the "gurgling" sound of the starting electromagnetic switch appears, but the crankshaft does not rotate. This phenomenon is generally a "broken" fault of the battery.

    2. The temporary parking can be started every time, but the crankshaft can only be rotated when the parking time is long or the next day is started. This phenomenon belongs to the serious self-discharge of the battery, and its plates and separators are seriously aged, indicating that the battery is close to being scrapped.

    3. When starting, the starter suddenly rotates weakly, and is accompanied by the smell of burning rubber or smoke coming out of the battery, which is mostly due to poor contact between the pole pile and the pole pile clamp and the heating and burning.

    4. If the starter driving gear and the engine flywheel gear ring make an idling sound of collision when starting, there are two reasons: one is the deformation of the meshing cutting surface of the flywheel gear ring; Second, the gap between the starter drive gear and the flywheel gear ring is too large. The two can't be meshed, and the engine won't start.

    5. As soon as the main power switch is turned on, the starter drive gear will be meshed with the flywheel gear ring and rotate together. This kind of failure occurs, firstly, the holding coil of the electromagnetic switch of the starter is misconnected on the power supply binding post; The second is that the 3 wires on the key switch are connected wrongly, and the judgment method is: the starter drive gear does not rotate when the key is in the "0" position, and the motor drive gear is started to rotate together with the flywheel gear ring in the "2" position.

    6. When the start switch is turned to the starting position, the engine cannot be started, and there is no other phenomenon. This kind of failure, first, the key and switch are not connected to the starting circuit due to wear; Second, the starter relay is not connected to the starter electromagnetic switch circuit; Third, the power switch is not connected to the main circuit.

    7. There is only a slight "click" sound when starting, and there is no response, which is caused by the issuance of the starting relay. At this time, as long as you press the tail of the solenoid to force the solenoid forward, the starting circuit can be turned on, so that the engine can be started.

    It can't catch fire. Generally, the situation that the fuel tank is out of oil is excluded.

    The car does not catch fire.

    The oil circuit and electrical circuit must be checked first.

    First see if your car has electricity.

    The horn is still not sounding.

    If there is electricity.

    There are also many factors that need to be checked such as the high-voltage pack, ignition coil, motor, spark plug, etc.

    The oil circuit pulls out the tube on the side of the fuel injector, and starts it to see if there is any oil sprayed out.

    If there is, then see if the fuel injector can produce oil.

    In short, there are many factors that make the car not start.

    Specifically, you need to take a closer look.

    If you put it on the R or D gear, it won't catch fire. There are also some manual transmission cars that will not catch fire if you don't step on the clutch for the following reasons:

    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 caused by the long-term headlights have not been turned off, and it is generally recommended to replace the battery in time after 2 years: the gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear.

    The third. 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.

    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.

    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 shorted.

    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!

    There are many reasons why the vehicle cannot start, such as: the steering wheel is deadlocked, the car is out of gas, the battery is out of power, and the gear does not return to neutral or P gear when parking.

  7. Anonymous users2024-02-09

    1.The battery is low or the terminal post is loose;

    2.Short circuit of the starting solenoid switch coil or poor contact of the contact plate;

    3.Ablation of starter relay contacts, short circuit or burnout of relay magnetic coils;

    3.The internal armature shaft of the starter is physically deformed, the brushes are worn, the spring contact is poor, and the rectifier is dirty.

    Generally, pay attention to the habits of electricity, automatic headlights or something is really not necessary, and all lights and electrical equipment must be turned off before turning off the engine, including air conditioning, audio, seat heating, etc. This ensures that the battery is 0 loaded before the next ignition. I have a car for 5 years, I didn't pay much attention when I first bought it, 2 years and a month, the battery was wasted, called rescue, replaced one, the original battery is also, since then I have paid attention to this side.

    The battery is badly depleted, leaving the vehicle with insufficient starting power. If it is an automatic transmission model, it is in gear, not in gear, and does not meet the starting conditions.

    1. Check whether the car battery has electricity. In fact, the failure to ignite and start is not necessarily that the battery is out of power, but the battery is not able to ignite and start. Because the car is equipped with a lot of other equipment, it is easy to cause circuit failure, how the battery itself is powered, press the horn to know, if the sound is very small, it means that the power is insufficient, if the sound is normal, it means that the power is normal.

    2. The steering wheel is in a deadbolt state. Because when parking, the steering wheel is not corrected, there will be a certain angle, if the angle is greater than 30, then the steering wheel will be automatically locked, which is equivalent to the car on the anti-theft lock, there is no way to start. Therefore, it is necessary to talk about the steering wheel to be corrected, the steering wheel lock should be lifted, and the car key should be turned to ignite and start, which will be solved.

    3. The gear does not return to neutral or P gear when parking. For automatic cars, if the vehicle is in D and R gears, and the car is started at this time, it is difficult to control the speed of the vehicle, and it will rush forward directly, and it is difficult to predict what will happen. And the car is generally not in P gear, and there will be a warning when starting the car to remind the driver.

    You need to hang the gear to the P gear.

    4. Check whether the oil quantity is sufficient. This can directly observe the fuel gauge display, whether it is below the red line, if it is, it means that the gasoline is not enough, this can not catch fire, you need to go to the gas station to refuel.

    5. Check whether antifreeze has been added. Because in winter, if antifreeze is not added, the waterway will be frozen, and other parts of the car will be damaged and will not be able to ignite, which will also cause the car to not start.

    1. The battery is out of powerSometimes when we get up in the morning and find that the car cannot start normally, it is likely that our trunk is not completely closed, and the trunk light is always on, resulting in the battery running out. 2. The spark plug cannot be ignited, the spark plug itself is easily damaged, the high-voltage line is short-circuited, etc., resulting in the spark plug can not be ignited, and the other is that the spark plug of poor quality is also caused to not start normally.

    1. The battery loses power.

    Solution: Use the power bank or find other vehicles for power rescue. Regular maintenance should be carried out, and the life of the battery and its capacity should be checked.

    2. The engine belt is aging. When the car reaches a certain kilometer, the engine belt will slip and crack.

    How to end it: Replace the engine belt immediately.

    3. The steering wheel is not back to right. This is a manufacturer's safety measure, when the steering wheel does not return to the center and exceeds a large angle when parking, the steering wheel will be locked, and the key may not be twisted.

    Solution: Turn the steering wheel hard and twist the key at the same time to unlock the steering wheel and drive the car.

    4. The starter is damaged. It may be due to damage caused by external forces or damage to its own life.

    Solution: Replace the starter.

    5. Ignition system failure. Check the working conditions of the ignition coils and spark plugs of each cylinder.

    Solution: Replace the live coil and spark plug if necessary.

    6. Fuel supply system failure. On the premise of ensuring that the fuel tank has oil, the fuel line pressure may be too low, or the fuel injector may be blocked.

    Solution: The fuel supply system should be overhauled, and the problem should be repaired in time.

    7. Failure of the air intake system. Check whether there is any fault in the throttle valve, idle control valve circuit, and air flow meter, and whether the air pipe and connector of the idle control valve are leaking.

    Solution: Go to a professional repair shop for repair and replacement.

    8. The car ran out of gas.

    If the car wants to have fewer failures, regular maintenance is indispensable, remind the maintenance technician to carefully check the aging degree of the parts on the car during maintenance, if there are potential safety hazards, it is recommended to replace them immediately, so that the car is always in a relatively good state, which can effectively avoid the situation that the car can not start.

    Will the car hurt if it doesn't start?

    Yes, incomplete combustion of the engine after long-term start-up can easily lead to carbon deposition and reduce charging efficiency, which directly affects the power performance of the car. This leads to difficulties in cold starts, increased fuel consumption, and more serious carbon deposits can cause the valve to be poorly sealed.

    What is carbon deposit.

    The impurities and non-flammable components contained in gasoline, after passing through the intake manifold, liquid residual colloids and incomplete combustion residues accumulate at the nozzle of the injector, and these black substances are commonly known as carbon deposits, which are formed without combustion products.

    The hazards of carbon deposits.

    Carbon deposition in the engine can lead to a series of problems such as poor work, unstable idling, reduced acceleration performance, high fuel consumption, and substandard exhaust gas. Carbon deposition in the intake pipe will affect the air intake effect, resulting in a significant reduction in the combustion condition of the engine and a serious reduction in engine power.

As for the problem you mentioned that the cool car does not get on the car, it is mainly caused by excessive carbon accumulation in the idle motor, air intake duct, intake valve and combustion chamber. Because of the excessive carbon deposit and dirt in the inlet duct, the cross-sectional area of the air passage changes, resulting in the mixture being too thick or too thin, so that the combustion is abnormal or the engine shakes or even cannot start after starting. Or because there is a problem with the fuel injector, there is leakage or too much carbon, resulting in the mixture being too thin during start-up, which makes it difficult to start. >>>More
