Karry suddenly turned off the engine, no oil supply, no high voltage electricity

It may be that there is a problem with the crankshaft position sensor.

Hello: There are generally two reasons for this situation.

First. It may be that the crankshaft position sensor is damaged. Or there is an abnormality in the crankshaft signal panel. The engine computer pole does not receive the cylinder judgment signal from the crankshaft position sensor. Resulting in no ignition and no fuel injection.

Second. It may be that the engine computer board itself is damaged. It will also cause non-ignition. No fuel injection.

I wish you a pleasant use of the car* [Car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

You will. At the same time, there is no oil and high voltage. Then it is possible that the position sensor of the crankshaft is damaged.

Or it is caused by poor contact of the plug of the wiring harness, I hope ours can solve your problem, I wish you a happy car! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello: What I said downstairs is good, but there may be another reason that the power supply insurance of the computer board is broken. You can use the decoder first to see if you can read the fault code, if it can mean that the ECU power supply is normal.

Focus on checking the crankshaft sensor. If it helps you. [Car questions, ask the car master.]

Summary. Hello, the vehicle suddenly turned off, the related reasons are the following points, first, the phenomenon caused by the insufficient fuel pressure of the vehicle gasoline pump, this is the need to detect the fuel pressure of the gasoline pump, if there is a problem or the pressure of the oil pump is unstable, the gasoline pump needs to be replaced in time. Second, this phenomenon caused by low idle speed of the vehicle engine, it is recommended to clean up the carbon deposits inside the throttle and engine, and then rematch the throttle.

Third, the crankshaft position sensor has a problem caused by this fault performance, this is the need to use a computer to read the fault of the crankshaft position sensor**, if there is a fault, you need to replace the new crankshaft position sensor. Fourth, check whether the engine of the vehicle is high, if the engine is high, it is easy to cause the phenomenon of stalling, then it is necessary to check whether the relevant sensors or fans are rotating normally. Fifth, the phenomenon caused by the virtual connection or damage of the relay related to the vehicle engine, this is the key to check whether there is a problem with the main relay.

Hello, the vehicle suddenly turned off, the relevant reasons are the following points, first, the vehicle gasoline pump pump oil pressure is insufficient erection caused by this phenomenon, this is the need to detect the gasoline pump oil pressure, if there is a problem or the oil pump pressure is unstable, you need to replace the gasoline pump in time. Second, this phenomenon caused by the low idle vertical chain of the vehicle engine, it is recommended to clean up the carbon deposits inside the throttle and the engine, and then rematch the throttle. Third, the crankshaft position sensor has a problem caused by this fault performance, this is the need to use a computer to read the crankshaft position sensor residual fiber liter fault**, if there is a fault, you need to replace the crankshaft position sensor.

Fourth, check whether the engine of the vehicle is high, if the engine is high, it is easy to cause the phenomenon of stalling, then it is necessary to check whether the relevant sensors or fans are rotating normally. Fifth, the phenomenon caused by the virtual connection or damage of the relay related to the vehicle engine, this is the key to check whether there is a problem with the main relay.

1. See if it is caused by hanging the wrong gear. Some people do not hang the gear in P gear when they stop and turn off the engine, but hang it directly in D gear. Because, if you hang the gear in D gear or R gear, there is no way to start the fire, and you can only start the fire if you hang the gear in P gear or N gear.

Therefore, when he wanted to start the fire again, he could not light it.

2. See if the car is out of gas. In addition to the battery running out of power, the fire cannot be ignited, and the car cannot be ignited when the gas is out. Usually this situation is because the engine is not turned off when you get out of the car, so that the fuel consumption is dried up and the electricity is used up, so the car has no way to ignite the fire.

3. Is there a fault in the gasoline pump? This reason is also somewhat similar to the running out of gasoline. If the starter can run normally when the ignition is ignited, but the car is not on, you need to check the gasoline line to see if there is a problem with the gasoline pump.

4. See if the starter is faulty. If the starter fails, this problem is very similar to the battery running out of power, and it will also cause the fire to not ignite.

5. Is there too much carbon deposited in the throttle place? If there is too much carbon deposited in the throttle, it will also not catch fire. In this case, just step on the accelerator a little bit to ignite the fire.

6. See if the crankshaft position sensor is faulty. There was damage here, and when the ignition was fired, the engine's computer had no way to receive the signal, and there was no way to control the spark plug for ignition. Hope it helps, hopefully.

Problems can occur in the ignition system's fuse, ignition controller, high-voltage pack, distributor, or crankshaft position sensor that is damaged or failing. If possible, use the computer to read the fault and data. Check the ignition controller; inspect the high-pressure pack; Check the distributors (if any); Check the crankshaft position sensor;

Inspect all high-voltage wire joints for looseness. If the high-voltage line is normal, it means that there is a problem with the high-voltage coil.

Summary. Consider the mechanical aspect, if the ignition suddenly stalls and there is a sound, it is most likely that there is a timing problem, causing the engine piston to fail to start the valve.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, this group of wisdom is caused by timing deviation or valve problems, the car suddenly turned off, after checking that there is a first oil signal, there is a spark plug jumping and can not start, check the mechanical aspect of exhaust blockage. The first reply has a time limit or dust, if you have any questions, you can reply and answer them in detail.

Suddenly, I turned off the fire, and I couldn't make a fire.

Consider the mechanical aspect, if the ignition suddenly stalls and there is a sound, it is most likely that there is a timing problem, causing the engine piston to fail to start the valve.

How to deal with it. Now start it, look at the speed of the engine, higher than 170 rpm, it is a problem of timing, this situation can only be dismantled engine replacement and valve dismantling carefully, now the wide shed jujube field can not be handled, find rescue.

Ask about custom messages].

Summary. It is very likely that the fuse of the ignition system or the ignition controller, the high-voltage bag, the distributor, etc., has appeared, and this is damaged or failed.

What is the reason why Chery Automobile cannot start without high-pressure fire?

It is very likely that the fuse of the ignition system or the ignition controller, the high-voltage bag, the distributor, etc., has appeared, and this is damaged or failed.

Insurance is good. The ignition coil plug has a live wire, no negative wire. There is no high pressure for the spark.

There is a fault in the transformer line, so there is no high voltage, check this transformer.

Are you a car repair professional? What car has a transformer, what is a voltage device, only high-voltage wires, high-voltage coils. Which transformer do you ask me to check?

There are three wires in the ignition wire of Chery engine, one positive electrode and one negative electrode start, you see if the line is faulty, one is with a pulse signal, see if there is any abnormality, if not, you check the computer version.

There's a sensor at that crankshaft position, and you can see if there's anything wrong with the sensor.

I also changed the computer board, and then I saw that the sensor sometimes has a slight pulse signal, but there is no high voltage.

If the pulse signal is weak, change it.

Three wires of the ignition coil. One is the positive connection fuse, and the other is the negative one. The other is connected to the computer version, the negative electrode and the signal line are connected to the computer version, and the signal line on the ignition coil is that there is no signal.

Which model and which car is this Chery yours in?

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:

1.The 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!

Why can't there be oil and fire?

There is a driving car encyclopedia. Concern.

The main reasons and solutions for the car not to start in the presence of oil and fire:

1. Common faults in the starting system: starter failure, insufficient battery power. The battery is severely starved and the vehicle cannot be started.

Resolution. The voltage can be simply measured with a multimeter.

If the voltage value is less than 10V, the battery cannot start. The voltage should preferably be above 12V.

When the battery is low, the engine can be started by charging the charger or starting with electricity.

If the starter fails, a multimeter can be used to measure whether the starter has a supply voltage.

If the starter has voltage and does not operate, it means that the starter is damaged and needs to be replaced at the repair shop.

2. Ignition system failure: ignition obstacle.

It may be that the spark plug is electrocuted and the oil is contaminated. At the same time, see if the carbon deposits on the spark plug are very serious, and generally replace the spark plug after 40,000 kilometers.

Solution: You can try to remove the spark plug and clean it, then load it into the car, start it, and see if it is normal.

3. Oil supply problem: It may be that the flow of gasoline is blocked and some injectors are faulty.

Resolution. Put the car in a warm environment, and the car will start after a while, or it can be completely solved by cleaning the oil circuit.

In addition, if there is a carburetor, you can see whether the interface glue with the engine is loose and whether there is leakage.

4. The steering wheel is locked: The steering wheel is locked as a normal anti-theft function. This happens because the steering wheel twists after the vehicle is closed. At this time, the on-board computer will think that the vehicle has been stolen and automatically activate the anti-theft function.

Solution: Turn the car key to start and turn the steering wheel at the same time. If it is an automatic transmission model, apply the brakes.

5. Fuel injector is blocked: Check whether the fuel injector of the car is blocked by too much carbon deposit.

Solution: Clean up the fuel injector into the friend.

6. When the gasoline pump fails, the oil cannot catch fire;

Solution: Go to a professional maintenance point to overhaul the gasoline pump.

7. If the gear is hung up incorrectly, there will be oil that cannot catch fire.

Solution: Check the blue state gear and hang the gear correctly.

8. The crankshaft position sensor is faulty, which will cause the oil to fail to ignite;

Solution: At this time, it is necessary to go to a professional maintenance point to overhaul the crankshaft position sensor.

9. When there is too much carbon accumulation on the throttle, it will affect the ignition, resulting in the oil not ignition;

Solution: Clean up the carbon deposits on the throttle valve in time or go to a professional maintenance organization for parts replacement and maintenance.

10. No antifreeze is added.

Solution: Antifreeze should be added in time.

If the car still can't start, it is recommended to go to the 4S shop to check the diagnostic computer to see if there are any fault codes and eliminate them one by one.
