Chang an New Leopard suddenly stopped the fire while driving normally, and the table showed what the

Fault situation and analysis: 1The manual transmission of the car was running normally, and suddenly it turned off, and when it turned off, I leaned on the side of the road and continued to turn on the fire, but it turned on and off, and it turned off and turned off.

If the car can ignite, it means that the engine ignition system is normal. However, if the engine stalls suddenly, you need to check the engine oil supply system. According to the phenomenon you provided, it is possible that the engine oil supply is abnormal.

If it is a diesel vehicle, you do not need to consider the ignition system. 2.Turned on and off, turned on and off, and the engine fault light came on.

This phenomenon may be caused by abnormal fuel pressure. According to the analysis of the principle of the oil circuit, it may be that the oil pressure is abnormal, or there are many impurities in the oil. 3.

A few days ago, there seemed to be a fuel cut during driving, but it didn't turn off. If the oil pressure in the oil circuit is abnormal, but there is still oil supply, the engine will not turn off. Solution:

1.Take the car to a garage and check the engine for faults with an engine failure analyzer or engine decoder**. 2.

Check whether the automobile fuel pump circuit is working properly. And detect whether the working oil pressure in the oil pipe is normal. The fuel pump will also wear out after working for a long time, and the wiring will also be poorly connected or broken.

3.Detect whether the oil pressure sensor circuit is working properly. 4.

Disassemble the fuel filter and check the contamination status of the filter. Although it is recommended that the fuel oil filter be replaced once every 40,000 to 50,000 kilometers, the fuel used by different vehicles is different, the oil quality of refueling is different, and the position of the oil from the oil storage tank in the refueling is not the same (there will be slightly more impurities in the oil at the bottom of the oil storage tank at the bottom of the gas station), and the use of the fuel oil filter is completely different. Therefore, it is necessary to disassemble or replace the fuel oil filter directly.

Through the above detection, this problem can be solved after analyzing the engine fault code. Hope mine can help you.

1. Since the fault light has alarmed, please use the determinator directly to see what the fault is 2. Whether the gasoline added last time is reliable.

Car engines.

The fault light should not be on when it is normal, but it should be on during self-test. If the car engine is normal and the fault light does not light up during the self-test, it should be the fault light is damaged or the fuse is broken.

Burnout. Common faults and troubleshooting methods of automobile engines.

When the automobile engine is not working properly, and the self-diagnosis system does not have a fault code output, it is especially necessary to rely on the operator's inspection and judgment to determine the nature of the fault and the location of the fault. The author now summarizes the common faults of automobile engines as follows:

The engine does not start.

1) Fault phenomenon: turn on the ignition switch, turn the ignition switch to the starting position, and the engine cannot start.

2) Possible causes of failure:

a.The engine cannot rotate or rotates too slowly due to the failure of the starting system: the battery is not stored enough, the electrode pile clamp is loose or the electrode pile is seriously oxidized; The main fuse of the circuit is broken; Ignition switch failure; starter failure; The starting line is broken or the line connector is in poor contact.

b.Ignition system failure: Ignition coil.

Poor work, resulting in weak or no high-voltage sparks; ignition failure; The ignition time is incorrect.

c.Fuel injection system failure: There is no fuel in the tank; The fuel pump is not working or the pump oil pressure is too low; Fuel line leakage and deformation; The disconnect relay is disconnected; The fuel pressure regulator is not working well; The fuel filter is too dirty.

d.Air intake system failure: Failure of the idle control valve or its control line; Idle control valve air pipe rupture or joint leakage; The air flow meter is faulty.

Summary. Hello, the car can not start this situation, is divided into two aspects, the first is that the vehicle starts without any response, then this situation 1: first of all, you need to check whether the battery power loss caused by this phenomenon?

If the battery is out of power, you need to charge the battery or replace it with a new one. 2: In the case of making sure that the battery does not lose power, focus on checking whether there is a problem with the vehicle starter or whether the anti-theft is locked, 3:

If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter. 4: If there is a problem with the anti-theft system, you need to re-do the anti-theft matching.

The second major aspect is that the vehicle engine can rotate, but does not catch fire, then this situation focuses on checking, 1: whether the gasoline pump oil pressure is insufficient or the vehicle engine is not ignition, 2: if the pump oil pressure is insufficient, this situation needs to replace the gasoline pump.

Check the fuse or wiring of the gasoline pump. 3: If it is not ignited, focus on checking the crankshaft position, sensor and ignition coil.

Your bureau believes that the car can not start this situation, is divided into two aspects, the first is that the vehicle starts without any response, then this situation 1: first of all, you need to check whether the battery loss of Tong Jian wheel electric caused by this phenomenon? If the battery is out of power, you need to charge the battery or replace it with a new one.

2: In the case of making sure that the battery does not lose power, focus on checking whether the vehicle starter is a problem or whether the anti-theft is locked, 3: If there is a problem with the starter, you need to check the corresponding control circuit of the starter or replace the starter.

4: If there is a problem with the anti-theft system, you need to re-do the anti-theft matching. The second major aspect is that the vehicle engine can turn, but it does not catch fire, so this situation is to focus on checking, 1:

Is it that the fuel pressure of the gasoline pump is insufficient or the engine of the vehicle is not ignition, 2: If the pump oil pressure is insufficient, the gasoline pump needs to be replaced in this case. Check the fuse or wiring of the gasoline pump.

3: If the sail is not ignited, focus on checking the crankshaft position, sensor and ignition coil. The above two aspects are the relevant reasons for the vehicle to not start, as well as the solutions, it is recommended to make a relevant reference!

No ignition. Sometimes it's good and sometimes it's bad.

If you do not ignite, check the crankshaft position sensor first.

The crankshaft has been checked, no problem.

When the vehicle is not ignition, does the engine fault light on the dashboard turn on?

No faulty lights. I mean that when the vehicle is inspected normally, the engine fault light is not on?

Not lit. If the spring is not bright, then this one should check the power supply line of the computer version to see if there is a problem? Can the normal computer decode the Rubber Alarm connect to read the fault**?

Summary. Hello, glad to answer for you. What is the reason why Changan New Leopard does not catch fire when it is ignited, and it is improper operation or improper operation of car parts:

For example, there is no gas, there is no electricity, the gear is wrong, and these situations are quite common. Car parts: Fuel injector clogged.

Usually, nozzle clogging is caused by impurities in the fuel that is blocking the nozzle channel. At a certain temperature, the unstable components in gasoline undergo a chemical reaction to form a gelatinous viscous substance. These substances can clog the needle valves and valve holes of the injectors, which can affect the performance of the engine, causing a drop in power and the engine not working properly.

So sometimes it will be hot, sometimes it won't.

Hello, glad to answer for you. What is the reason why Chang'an New Leopard does not catch fire when it is ignited, and it is improper operation or improper operation of car parts: such as running out of oil, running out of electricity, and having the wrong gear, and these situations are quite common.

Car parts: Fuel injector clogged. Usually, nozzle clogging is caused by impurities in the fuel that is blocking the nozzle channel.

At a certain temperature, the unstable components in gasoline undergo a chemical reaction to form a gelatinous viscous substance. These substances can clog the needle valves and valve holes of the injectors, which can affect the performance of the engine, causing a drop in power and the engine not working properly. So sometimes it will be hot, sometimes it won't.

The reasons for the ignition of Chang'an New Leopard are as follows: The second reason: there is carbon deposition in the throttle valve.

Carbon deposition in the engine has a great impact on the engine, which will reduce the engine power and make the power output uneven. It will also increase fuel consumption, and it will also cause difficulties in cold starts, resulting in difficult ignition and difficult driving. The third reason:

There is a problem with the fuel system. The oil pump is damaged and the oil circuit is blocked, which will lead to insufficient fuel supply, not enough fuel to participate in combustion, resulting in low concentration of mixture, making the spark plug not easy to ignite and the car not easy to ignite.

When it doesn't start, it doesn't ignite.

This situation is 1. The battery is insufficient. 2. Oil circuit failure.

The battery is low. The battery of the vehicle is insufficient, or the battery is faulty, which will cause the vehicle to fail to ignite, in this case, we need to charge the battery or repair and replace the battery, and then we can re-ignite. Oil circuit failure.

Stalling caused by oil circuit failure is often a sign of engine weakness and the refueling pedal stepping on cotton. Oil circuit failures may occur in the following areas: oil pump failure, oil circuit failure, oil filter blockage, spark plug carbon deposit, fuel injector damage.

Don't catch fire when it's on fire, don't light it when it's not on fire.

According to the information you provided, this is a failure of the starting system and ignition system.

The battery damage in the starting system does not have enough power to drive the starter motor, so the vehicle cannot start, and there is another possibility that the starter motor is damaged. And the vehicle's spark plug failed, and the ignition module failed, resulting in the spark plug failing to ignite, and all vehicles that could not ignite the mixture could not start.

Summary. Hello, the vehicle sometimes starts, sometimes does not start, the relevant reasons and how to deal with it are as follows. First, first check the pressure of the fuel pump, if there is a problem with the fuel pump oil, it will also lead to this phenomenon and need to be replaced with a new fuel pump.

The second is the problem of related sensors, focusing on checking the crankshaft position sensor. Third, use the computer to read the fault**, and do the corresponding diagnosis and analysis according to the fault**.

No problem with the fuel pump.

When the vehicle fails to start, does it inject fuel or does it not ignite?Has this ever been tested?

No ignition. Check the crankshaft position sensor first.

No problem with the crankshaft.

Then you need to check the computer version of the vehicle and the relevant power supply lines.

Summary. When the starter gear is usually in a free state, it does not rotate, when the engine needs to be started, the electric gate switch is twisted to the starting position, the relay is connected to the electromagnet above the starter, the electromagnet drives the starter gear to mesh with the engine flywheel gear ring, and the electromagnet is also connected to the starter switch, the starter rotates, drives the engine to rotate, and the electromagnet is powered off after successful starting, and the starter gear is reset at the same time as the power is cut off and stops running.

That is, there is a problem with the line, check the constant current of the ignition coil, and basically find the problem.

This should be a problem on the line, you are the water temperature of the sensor nuclear dissipation to measure how much voltage, the ignition coil has no constant electricity, there must be a question.

How to check. The grease nozzle is dead, and the ignition coil is also powered.

There is a full circuit diagram no.

When the engine needs to be started, the electric gate switch is twisted to the starting position, the relay is connected to the electromagnet above the starter, the electromagnet drives the starter gear to mesh with the engine flywheel gear ring, and the electromagnet is also connected to the starter switch, the starter rotates, drives the engine to rotate, and the electromagnet is powered off after the successful start, and the starter gear is closed and reset at the same time to stop the permeable operation.

I can't check it.

How to fix. Repair shop, I can only give a general mind.

Summary. Check the line first. Restore the line. Then check the main relay. Check the flame-out lever on the high-pressure oil pump and the control mechanism of the flame-out lever. The flame-out lever is designed to prevent the high-pressure oil pump from pressurizing oil into the injector.

Hello, is it impossible to turn off the fire. Will the turn signal be turned off when the safety is removed?

That's right. Hello, if you are in this case, the electronic flame breaker is broken, and you may not be able to drive the car after the ignition. Also check the spark plug crankshaft position sensor.

Taxi. It's just that the daughter-in-law can't

The turning light insurance is a daughter-in-law.

Have you ever changed the car. Check the line first. Restore the line. Then check the main relay.

Check the control mechanism of the flame-out pull source bib rod and the flame-out pull rod on the high-pressure oil pump on the diesel engine. The problem must be in that shout. The Hail Flame Out Tie Bar is designed to prevent the high-pressure oil pump from pressurizing oil into the injector.

Gasoline engine. It is recommended to focus on the ignition switch itself, but it should also be distinguished from the original vehicle circuit design.

The ignition switch is fine.

Check the line first. Restore the line. Then check the main relay bush ruler digging appliance. Check the flame-out lever and the control mechanism of the flame-out lever on the high-pressure oil pump. The flame-out lever is used to prevent the high-pressure oil pump from seeping into the injector.
