What is the reason why the Buick car died after 2 3 fire

1. Common ignition fault phenomena.

1. The engine has poor running stability, deflagration and easy overheating.

2. If there is reversal, idling and deflagration when the engine starts at the time of rapid acceleration, it is premature ignition.

3. The engine is stuffy and weak, easy to overheat, the exhaust pipe emits black smoke, and the ignition is too late.

2. Troubleshooting and diagnosis of fault causes.

1) Cause of failure:

1. Improper adjustment of ignition timing, adjustment of ignition timing;

2. If the ignition advance angle centrifugal adjustment device on the distributor fails and the vacuum adjustment device fails or the pipeline connection is not sealed, the adjustment device should be overhauled. Among them, improper ignition timing adjustment is the most common.

3. Improper diagnosis method of engine ignition time:

4. Use the ignition timing instrument for detection.

2) Maintenance and fault judgment.

Phenomenon: The engine is not running smoothly, there is a reversal when the engine starts, and there is a deflagration at idle speed and rapid acceleration, which is premature ignition.

Elimination method: connect the ignition tester, adjust the ignition and hand it over to the specified value in advance.

Ignition is too late and repaired.

Phenomenon: the engine is stuffy and overheated, the exhaust pipe emits black smoke, and the ignition is too late when the gun or carburetor is tempered.

Exclusion method: Connect the ignition tester to adjust the specified value of the ignition advance corner.

Hello, this one needs to check if the gasoline filter is clogged.

Hello, can you get on the car with the accelerator.

Check whether the throttle and idle motor are too dirty.

Does the starter turn around? Check the battery!

My car gives you the same situation, how do you solve it.

The battery has electricity, fuel injection and ignition are eating, it may be that the starter motor is damaged and the flywheel cannot be driven, so the vehicle can not start, check the starter motor, if it is damaged, it needs to be replaced.

Steering wheel locking: If the steering wheel is not back to the right when parking, when it is at a slightly larger angle, the steering wheel will automatically lock, which is also an anti-theft measure, at this time the key may not be screwed, resulting in ignition.

2.Battery failure: If the headlights are not turned off for a long time, it will lead to power loss, or the battery life will expire.

How many kilometers does your current car run Is it often a short-distance drive not on the high speed If it is not running at high speed after 30000, it is generally the throttle carbon deposition fuel injector The inlet is blocked and needs to be cleaned Cleaning must go to the 4S shop Otherwise, it will idle high after washing In the 4S shop will give you the throttle to learn to reset You can't do it outside.

1. Out of gas.

If the fuel gauge shows that it is below the red line, it will not ignite.

2. The battery is out of power.

It may be due to the loss of power or the expiration of the battery life due to the long-term headlights have not been turned off, and it is generally recommended to replace the battery in time after 2 years. 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.

3. The gear is wrong.

When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

Brother, it's the gasoline pump that is broken, do you often drive at a loss of fuel?

When my car is hitting, there is a sound of oil, but it can't be hit, what is the reason?

Ignition system: It may be that the spark plug of the vehicle is faulty, and the ignition module is faulty, resulting in the spark plug not being ignited, and all vehicles that cannot ignite the mixture cannot be started.

Fuel injection system: It may be in the fuel injection system, the fuel injector is faulty, the fuel supply pressure of the gasoline pump is insufficient, and the fuel injection nozzle line is faulty, so the vehicle cannot be started.

Starting system: It may be that the battery in the starting system is damaged and does not have enough power to drive the starting motor, so the vehicle cannot start, and another may be caused by damage to the starting motor.

Hello, in this case, first check whether the ignition coil has power supply, no power supply is a line problem, and if there is electricity, the ignition coil is broken [car problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, this is caused by a lot of carbon accumulation in the valve, which leads to poor valve closure. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello reasons: 1There are individual cylinders with low cylinder pressure, 2. There are individual cylinders with poor ignition, 3

Individual cylinder fuel injector is seriously blocked, check whether the pressure of several cylinders is consistent, whether the ignition system of each cylinder is normal, whether the ignition coil, spark plug, and high-voltage line are normal, check whether all fuel injectors are blocked and leakage, and find out the fault, please replace it at the repair station or repair shop in time, I hope it can help you, I wish you a happy car. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

It's all normal, why do you still jump the fault light.

According to your above description, it is easy for a hot car to stall and fail, and for this model, the general DAO is mostly due to the following reasons:

1. Ignition tempering coil (and poor power supply tie) to answer the fault;

2. Failure of the speed sensor and engine control unit;

3. There is a fault in the fuel supply system.

Desktop version or thread oxidation.

I'm the same, I don't know how to fix it, so I ask the great god to enlighten it.

Brother, same problem, help.

Hello, how did you solve it? I've also encountered a problem with the sample, and even the computer board has been replaced.

Didn't check the spark plugs? And the sub-cylinder line?

Your problem has been solved, master, I have a car in my hand, and I can't find out the reason! Both camshaft sensors are unplugged and run without fire!

Hello landlord, has the problem been solved.

Brother: What's the problem?

The fault of the fire in the second or third cylinder of your car, this is hard to say. There are so many reasons why this can happen.

This is the case with the car, and it would be nice to replace the spark plugs and cylinder wires.

I have run tens of thousands of kilometers, and it is not difficult to find out the reason for the normal situation you said, and ignition is so many necessary conditions, which are easy to check.
