What s wrong with the fire in the light section of Wuling, and what is the problem with the weak ign

If the car is out of flame, it is recommended to check whether there is a problem with the ignition coil and replace it in time.

This situation should be caused by a lack of cylinder or a problem with the ignition coil.

Hello, the car is well maintained. There's nothing wrong with it.

Hello, use the computer to check whether there is a problem with a cylinder, and then check whether there is a problem with the cylinder wire, spark plug, and ignition coil.

1. The spring of the movable contact arm of the breaker in the distributor is too soft, resulting in the slow or unable to close the contact at high speed. In this case, the current on the primary side of the ignition coil decreases or cannot be turned on, and the high voltage on the secondary side is insufficient or cannot generate high voltage, resulting in a fire failure.

2. The bearing of the distributor is worn too much. After the bearing is worn and loose, the change of contact clearance, coupled with the violent swing of the distributor shaft at high speed, directly affects the generation of high-voltage sparks, resulting in high-speed fire failure.

3. The individual edges and corners of the cam of the cut-off are too worn. At high speeds, the cam cannot open the contacts, and individual cylinders are fired off due to the absence of high-voltage electricity.

4. The contact surface of the contact of the breaker is skewed. Due to the increase in contact resistance, the high-voltage voltage is insufficient at high speed and the fire is broken.

Ignition of a cold car will cause incomplete combustion of the mixture, and if the hot car still smells of gasoline, it will be faulty. The cause of the failure may be that the mixture is too thick, the ignition gap of the spark plug is large, the ignition is incomplete, and the organic carbon atomization of the throttle and fuel injector is poor.

Hello landlord! It is advisable to check the spark plug and spark wreath for the fire break.

Hello, this can be checked to see if it is caused by the failure of the spark plug and the fire coil.

Hello, glad to answer for you :

The reasons for the poor start are: late ignition time, weak high-voltage fire, and slight leakage of the fire head. Excessive spark plug clearance, insufficient battery voltage, etc., will cause the engine to be difficult to start. It is recommended to go to a professional repair shop to check and rule it out.

I hope to help you, if you are satisfied, I will do it. Thank you.

The HLM car cannot be started, the idle speed is unstable, the speed is high and low, and the inspection items are as follows:

1. The battery voltage of the car is low; Specific detection method: test the battery voltage with a three-purpose meter voltage level, if it is below 10V, it is recommended to replace it. If it is around 11V, it is barely used; Be prepared for replacement. It can be used above 12V;

2. Check whether it is caused by carbon deposits; If you travel about 20,000 km, focus on checking and cleaning the throttle;

3. Inspect, test and replace spark plugs;

4. Confirm the quality of the gasoline added;

5. Detecting the ignition switch;

6. Test and detect the starter, gasoline pump, sensor and other related components of the starting and oil supply system;

7. After powering on, do not start immediately, wait for 30 seconds to 1 minute, and then ignite; See if it works;

Regardless of any of the above situations, pay attention to the time when the car cannot be hit once, be sure to play again after an interval of 15-30 seconds, so as to protect the battery but not generate power and prolong its service life.

Anonymous usersThere are many reasons why it can't be activated:

1. Oil circuit failure (oil pump does not oil).

2. The fuel injector line is faulty (can not be injected).

3. Ignition system failure (spark plug does not ignite, or ignition is too weak).

4. The timing belt is broken, or the teeth are jumped, resulting in the wrong gas distribution.

5. The inlet and row branch pipes are not passable.

6. The cylinder pressure is too low and the cylinder seal is poor.

7. The starter or battery is faulty, and the starting speed is too low.

8. Poor contact of ignition switch (including anti-theft system), resulting in no power in the system.

9. Mechanical failure, (such as chemical tile, connecting rod breakage, etc.).

The cause of weak ignition may be a problem with the spark plug, a slight leakage from the distributor head, or a problem with the high-voltage pack.
