My car won t start maybe there s something wrong!

1. The battery loses power, or the connecting wire is broken or the joint is loose; 2. The contact of the starting relay is seriously ablated or its coil is broken; 3. The contact of the starter electromagnetic switch is seriously ablated or its suction coil is broken; 4. The internal winding of the starter DC motor is broken or short-circuited; 5. The armature shaft of the starter is bent, and the gap between the shaft and the bearing is too tight; 6. The commutator is seriously ablated, the brush is worn too much, the brush is stuck in the brush holder or the brush spring is too soft.

Common points of failure are: the battery is faulty and cannot store power. If you can only hear the sound of the starter when starting the car, it is likely that the battery will not start due to a loss of battery power.

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 engine, turn on the ignition switch, and observe whether there is oil flowing out when the instrument light is on (the starter is not running). If there is oil outflow, there is no problem with the oil supply system, and if there is no oil, continue to check.

There are many reasons why the car cannot start, there is a problem with the first start control line, and there is a problem with the starter itself. Then there may also be a problem with the battery switch that starts, I hope the above comments can help you. FYI, thanks!

1. The battery loses power.

Solution: Use the electric treasure or find other vehicles for electric rescue.

2. The engine belt is aging.

Solution: When the car reaches a certain kilometer, the engine belt will slip and crack; The engine belt needs to be replaced immediately.

3. The steering wheel is not back to right.

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.

Solution: It may be caused by external force or damage to its own life; Replace the starter immediately.

5. Ignition system failure.

Solution: Check the working condition of the ignition coil and spark plug of each cylinder, and replace it if needed.

6. Fuel supply system failure.

Solution: On the premise of ensuring that the fuel tank has oil, the fuel pipe pressure may be too low, or the fuel injector is blocked, and the fuel supply system should be overhauled.

7. Failure of the air intake system.

Solution: Go to the 4S shop to overhaul the air intake system.

8. Check whether the gear is hung in P gear.

Solution: Hook the gear back to P.

9. Serious carbon deposition in automobiles.

After the car has serious carbon deposits, it will also affect the normal start of the car, and the phenomenon of shaking may also occur when the car is idling.

Solution: Go to the 4S shop to clean the throttle valve or clean the intake duct to alleviate it.

10. The car is out of gas.

Starting a car with no fuel is definitely a loss problem, which is a mistake that many careless car owners will make.

Solution: When driving, you need to check the oil of the car, and if there is a shortage of fuel, you need to add it in time to avoid the situation that the car cannot start because of insufficient fuel when driving.

11. The use of inferior engine oil: when the cool car starts, due to the factors of cylinder pressure, speed and temperature, it is difficult to ignite the inferior engine oil and cannot be started.

12. Start relay card issuance: There is only a slight click sound when starting, and there is no response, which is caused by the starting relay card issuance.

Solution: At this time, just press the tail of the electromagnet to force the electromagnet to move forward, and the starting circuit can be turned on, so that the engine can start.

13. Spark plug failure: It may be that the spark plug of the vehicle is faulty, and the ignition module is faulty, resulting in the spark plug being unable to ignite, resulting in the vehicle being unable to start.

Solution: In this case, it is recommended to change the spark plug with a more resistant beam.

How big is the engine whether it is electric or hand-started.

First, check whether the gasoline is smooth and whether the spark is normal.

Method: Directly remove the spark plug, plug the spark plug hole with your fingers, pull the pull plate several times with one hand, and smell whether your fingers smell of gasoline after the front eggplant is withdrawn.

If there is a number of regrets, the oil circuit is normal If not, check the oil circuit (oil switch, carburetor, etc.) Connect the spark plug to the high-pressure cap, slide its thread contact potato to the bolt or technical part of the body, pull the pull plate, check whether there is a spark beating at the spark plug, if it is normal, if not, check the flame-out switch High-voltage package Spark plug and other circuits In addition, when blocking the spark plug hole with your fingers, you can feel the impact and suction of the pop, if it is normal, if not, check the valve clearance, whether the valve is stuck, etc.

Once these three checks are completed or ruled out, they should be able to start normally.

In addition, if it is with an oil alarm, you should check whether the oil is enough, and after adding enough oil, you can directly pull out a line directly below the body, and you can eliminate the oil series fault.

There are many reasons why a vehicle will not start, such as battery failure, spark plug ignition failure, faulty starting circuit, use of inferior engine oil, etc. , all of which contribute to this phenomenon. It is recommended to troubleshoot in time.

1.The battery is dead.

Since the voltage at startup is lower than the minimum voltage of the computer, the engine computer does not work and cannot start. In the case of reed socks, the battery should be charged or replaced.

2.The spark plug cannot be ignited.

The spark plug itself is easily damaged, the high-voltage line is short-circuited, etc. , which causes the spark plug to fail to ignite, and the other is the poor quality of the spark plug, which also causes the spark plug to fail to start properly. In this case, it is advisable to replace the spark plug.

3.Faulty startup circuit.

There is only a slight "click" sound when starting, and there is no response, which is caused by the starting relay card issuance. At this time, it is only necessary to press the tail of the electromagnet to force the electromagnet to move forward, and the starting circuit can be turned on and the engine can be started.

4.Use low-quality motor oil.

When the cold car starts, due to the residual cavity reasons such as cylinder pressure, speed, and temperature, it is difficult to ignite the inferior engine oil and cannot be started with the excitation. It is recommended to use the original recommended oil, or the quality is better than that of a fully synthetic oil.
