Excuse me, when the red flag H7, 1.8T was first built, it could not be started once. What is the reason why it needs to be started twice before it can be ignited?

What are the reasons for the bad cold start of the car: insufficient battery power; Insufficient compression pressure of engine cylinder; The throttle valve is seriously dirty and the air intake is insufficient; Engine coolant temperature sensor failure; The oil is too poor to reach the corresponding calorific value, resulting in a small power output of combustion. As you said, the noise is similar to that of a dead battery. If the battery works normally, check the battery connection circuit, relay and electromagnetic switch. It is best to maintain the starter.

The pressure of the oil pump is low, which is quite different from the sound of the battery being dead. You are really misleading.

The new car will not start when it is started for the first time, and it will work normally for the second time because there is air in the oil circuit. You can turn on the key and let the fuel pump work for a few seconds before starting.

I think there are two reasons.

First, the gear is wrong.

Second, when there is a fire, you step on the accelerator too deeply.

1, an automatic car can only be ignited if the gear is in the P gear, otherwise the car cannot be ignited;

2. The throttle was stepped on too deeply, causing the throttle to be flooded, so the car couldn't hit it.

It is normal for some vehicles to brake. It may be that the vehicle has been parked for a long time, the oil pipe is empty, and the oil entering the engine is delayed. If it doesn't catch fire repeatedly, the fourth S shop is responsible for repairing and replacing parts, free of charge.
