Help, the cold car ignition can only be started after a second of delay, what is the situation

1. The reason for the ignition start delay.

1. The oil is not good: if the car suddenly starts normally to delay the start, then you must first think about whether you have changed to gasoline of different grades and gasoline in different places in the near future.

2. Carbon deposits in the car.

or dirty parts.

a. Throttle.

The carbon deposition of the throttle will affect the perception of the throttle and air intake, resulting in the lag or even error of the computer transmission signal, resulting in the vehicle not being able to start;

b. Fuel injector: It is easy to adhere some gum to the fuel injector, which will block the normal amount of fuel injection, resulting in poor atomization of gasoline, so that the ignition is delayed and the car is difficult to start;

c. Spark plug.

If there is a lot of carbon deposition in the spark plug or there is air leakage at the joint between the metal and the porcelain, it will cause poor ignition;

d. Battery: Dirty battery binding posts may also cause poor conductivity, which will affect ignition; Of course, the lack of battery power may also cause a delay in ignition start-up;

3. The starter relay is faulty;

4. The starting motor is faulty;

5. The viscosity of the engine oil is not suitable: for example, when the temperature is very low, the viscosity of the engine oil is high, resulting in slow oil circulation and dry friction of the machinery, so it is difficult to start, and at the same time, it is very harmful to the car;

6. There is a problem with the ignition switch;

7. Carbon canister solenoid valve.

Faulty: The ignition is weak after exposure, but there is no secondary ignition, generally there is a problem with the solenoid valve of the carbon canister, because the role of transpiration after gasoline exposure is particularly large, and the valve of the carbon tank valve is not well sealed, and it is easy to flood the cylinder that is the wet wall.

8. Ignition timing proofreading.

There is a problem; 9. a camshaft.

Sensor failure: In the case of confirming that there is no problem with the timing calibration, you can focus on checking whether the camshaft position sensor is working properly;

10. Insufficient oil pressure: gasoline pump pressure relief, poor fuel injector sealing, etc., will cause insufficient gasoline pressure, so that the ignition time will be prolonged;

2. Summary. The car starts delayed, and it is difficult to start, whether it occurs when the car is hot or cold, and it is inseparable from the three problems of oil circuit, circuit, and oil-electricity coordination. As long as the maintenance personnel think through these three aspects, they will be able to quickly find the crux of the problem; Also as a friend of the owner, according to the usual use of the car, and then compare the above content, I believe that you can also have a more accurate conjecture, and you will have more confidence in finding someone to repair.

Hello, if the normal ignition is delayed, there will be two problems, one is carbon deposition, and the other is whether the pressure of the oil pump is enough, first check whether the carbon deposition of the throttle is too much, it is recommended to sober up, and then the pressure gauge to detect the oil pump pressure.

When the cold car starts, because the pressure of the engine oil has not yet come up, there may be some delay or abnormal sound.

Normal, because the weather is cold and the cylinder pressure is also a little larger, and the delay is one second normal phenomenon.

When the car starts in a cold weather, it does take a little time. This is all normal and there is no need to worry too much.

Mine also encountered the same problem, generally the fuel tank oil pressure is insufficient, the ignition produces a low concentration of fuel mist, the car key is turned on and off a few more times, if it still doesn't work, it may be a spark plug or fuel filter problem.

Hello As you said, it is recommended to check whether the battery voltage is normal, whether there is a problem with the motor, which may be caused by insufficient speed, and then check the gasoline pressure and the use of spark plugs.

The main reason is that the weather is cold, and the mixture of air and oil is not very good, and the second is that the valve is a little gelatinous and the cylinder pressure is low when the car is cold. Hope it helps.

Hello! Check whether the battery power status is a little insufficient, and then check whether the vehicle throttle volume carbon is too much and the air intake is insufficient.

If this is the case with the car, it is recommended to check whether the spark plug is caused by the problem.

Are you a diesel car? Diesel cars will be delayed in winter. If it's a petrol car, maybe your battery is failing.

Hello! This is generally caused by a dirty throttle valve of the car. This suggestion is to first check and clean the throttle valve of the car. The second is to check the oil pressure of the oil pump.

In this case, it should be that the car has some carbon deposits, and it is best to find a professional to test it.

You try to turn on the key a few more times (turn on the key without ignition), switch it a few times, and then turn on the ignition to see if there is still such a situation.

Hello! In this case, it is generally due to the carbon deposits inside the engine, or there is a problem with the starting system of the engine, it is recommended that you go to the repair shop for a comprehensive inspection, and then carry out repairs.

Hello, it is recommended to clean up the throttle to see if there is too much carbon deposit, and change the lower oil brand when changing the oil.

Hello, this car is not easy to start in a cold state, which may be caused by too much carbon accumulation in the engine.

Hello, according to your situation, it may be caused by more carbon deposits in the car engine, and it is recommended to clean the throttle.

If this is the case for you, it is best to check whether the battery voltage is normal, whether the starting speed is appropriate, and whether the oil pressure is normal.

Hello, this weather will be cold if there will be this phenomenon, don't worry, there is no problem with hot cars.

Hello, the cold car is not good to start should be the throttle is too dirty, it is recommended that you go to the repair shop to clean the throttle and clear the carbon deposits!

Hello, the cold car is not good to start should be caused by carbon deposits in the engine throttle or spark plug, it is recommended to clean up the carbon deposits.

Hello, this is likely to be caused by carbon deposits, which need to be cleaned by carbon deposits, which is estimated to be caused by too much carbon deposits.

If the ignition is only delayed, there is a problem with the spark plug, and it will be good to replace it with a new one; But there is also an abnormality in the instrument pointer, that is, there is a problem with the circuit, it may be that the electronic regulator is broken, and this problem is still checked by the computer at the maintenance point.

The long ignition time of the car needs to be analyzed according to different situations. If the ignition can start normally for a long time, it means that the ignition of the car is not stable. Conversely, if the ignition is not smooth, there may be a problem with the spark plug in the ignition system.

A higher ignition energy is required to start a cold car. If there is a problem with the spark plug and the gas mixture in the cylinder cannot be properly ignited, it will naturally be difficult to start.

However, if the ignition does not start properly after a long time, it is mainly due to the problems of the car battery, such as the loss of power of the car battery, the limitation of the car battery life, etc. In fact, a problem in the ignition system, air intake system, and fuel system can also cause the ignition time to be too long.

First of all, the slow ignition of the car does not necessarily cause problems with the car itself. Conversely, if the ignition of a cold car is slow, the normal ignition of a hot car may be related to the cold weather. In winter, the temperature is low, and when the cold car is started, the body temperature is low, and the fuel is difficult to atomize, resulting in the fuel injected into the cylinder cannot be fully mixed with the air, and the gasoline gasification rate drops sharply.

In addition, if the ignition reaction is slow in summer, there may be a problem with the spark plug in the ignition system. For example, if the electrode gap of the spark plug is too large and the service life reaches the limit, the ignition will be slow and the spark plug can be replaced. At the same time, ignition delay also involves fault causes such as damaged oxygen sensor, air intake system leakage, throttle blockage, low fuel pressure, incorrect ignition, low cylinder compression pressure, etc., which can lead to ignition delay.

Dear, what is the reason for the delay in the ignition of the car.

1. Reasons for ignition start delay 1. Oil is not good: If the car suddenly starts normally to delay starting, then you must first think about whether you have changed to gasoline of different brands and gasoline in different places in the near future. 2. Carbon deposits in the car or dirty parts A, throttle:

I hope it helps you [than the heart] [than the heart] [than the heart].

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

This winter is relatively cold, it is not easy to heat up, in fact, it will be a few seconds late, sometimes it can't be played for several minutes, which is also normal, because the fuel of the car will condense in the case of special coldAt this time, the spark plug has no way to ignite the fuel quickly, and the car engine cannot produce heat if it cannot ignite, so it will cause a vicious circle. <>

In the past, the old car, in the last century, there would be no fire in winter, so the car basically had to prepare a garage and put it in a similar indoor environment. But now it's different, now the car has antifreeze, even if it's cold outside, the car is not, it will delay for a while, and it won't say that there is no fire, antifreeze can indeed avoid the car's engine fuel and oil frozen, but it can't completely solve the problem of low temperature that is not easy to ignite, this problem will inevitably appear, and it is normal. <>

If you build a garage in your own home, then all around are closed, even if it is colder in winter, the garage will not be particularly cold, and it will not affect the normal ignition of the car. If there is no underground garage in the community is open-air, then the car may be more test of performance, because some cars add better antifreeze, the performance of the car itself is better, it is not easy to appear that it cannot catch fire, and some are not able to catch fire, especially cold on the nest. For example, in some Northeast regions, when it reaches minus 30 degrees Celsius and minus 40 degrees, many cars cannot catch fire, and they are afraid of freezing nests, which is real, and it will occur several times a year in winter.

As long as the area of their death is not the Northeast region, there is basically no colder place in our country than the Northeast region, and after the winter, it will reach more than 10 degrees below zero and more than 20 degrees below zero, which does not affect the normal use of the car, because this temperature is within the protection range of antifreeze. But if it comes to minus 40 degrees, then the effect of these antifreeze is very limited, although it is added, but it cannot guarantee the normal use of the car.

1. The cylinder pressure is low - the main reason. 2. The air filter is blocked, the air inlet is leaking, and the computer is not concentrated enough, resulting in the mixer being too thick or too thin. 3. The ignition voltage is insufficient due to the dampness of the spark plug and the decay of the ignition coil.

If this is the case, it is very likely that the fuel injector is blocked, it may be that the vehicle's throttle valve is very dirty, or it is possible that the spark plug is very badly damaged.

The reasons for this situation are generally gasoline pump pressure relief, fuel injector blockage will cause this problem, according to the specific situation to carry out the corresponding transformation, fault inspection, to ensure that the vehicle runs normally.

The car stalled a few seconds after starting the cold start for the following reasons:

1.Battery issues. If this is the reason, the owner can judge whether the horn is ringing, and the sound of the horn is obviously weaker than usual, or it is not ringing, then you can judge that the battery is low.

2.The oil-gas mixing ratio is inaccurate. It is present in both open-loop and closed-loop control. If the on-board computer makes a mistake in judgment, the actuator's control of the oil-gas mixture and ignition time will cause errors, thereby reducing the power output of the car and causing the car to not easily catch fire.

3.The ignition system power supply voltage is unstable. This factor is caused by dirty injectors, damaged canister solenoid valves, etc.

In addition, there are the following reasons why the car is not good to ignite

1. Battery problems. If this is the reason, the owner can judge by pressing the horn whether it sounds, the horn sound is obviously weaker than usual, or not loud, and the silver hall can be judged to be insufficient battery power.

2. The mixing ratio of oil and gas is not accurate, which exists in both open-loop and closed-loop control. If the judgment of the car computer is wrong, there will be an error in the control of the oil and gas mixing and ignition time through the actuator, thereby reducing the power output of the car, and the phenomenon of shaking will also lead to the car not catching fire.

3. The power supply voltage of the ignition system is unstable. This factor is caused by dirty fuel injectors, damaged canister solenoid valves, etc.

4. Injector dripping. Injector fuel injection is normal, but dripping is an additional fuel supply, so the more serious the injector dripping, the thicker the mixture, resulting in a hot car that is not good to start.
