What will happen if the regal solenoid valve is broken?

The engine is difficult to start, the engine loses power and the idle speed is unstable.

1. The failure of the solenoid valve causes the fuel not to be injected into the cylinder normally, which makes it difficult or impossible to start the engine.

2. The failure of solenoid valve leads to unstable or insufficient fuel injection, which leads to the decrease of engine power or poor acceleration.

3. The failure of the solenoid valve leads to unstable fuel injection, which in turn leads to unstable idle speed and jitter of the engine or abnormal speed change.
