17 What is the reason why the single-row fuel filler door of gasoline Kyle can't be opened?

Reason for not stepping on the accelerator: 1. It may be that the fuel injector is blocked, the oil pipe leaks and the power of the gasoline pump is reduced. 2. If it becomes weak when the body is tilted, it should be that there is something wrong with the gasoline filter of the fuel system. At this time, it is necessary to check whether there is a specific pressure gauge in the fuel pipeline. The engine knows that there is also a valve interface reserved for checking the fuel pressure: 3. Is the air filter or throttle system blocked? If these parts have problems, they can be repaired or replaced in time; 4. See if it is closed. The engine of a car should know that at least one cylinder is working abnormally or in a flameout state. Under normal circumstances, if one cylinder of the four-cylinder pilot does not start, the engine can still run. If it exceeds four cylinders, this symptom will decrease with the increase of the number of cylinders, and it is not easy to be detected.
