Whirring sound before starting

youngshag · Jun 25, 2014

As I go to start my Range Rover 4.6 petrol with gas conversion, there is a whirring noise behind the dash as if something is gearing up. It happens when I go to position 2 on the ignition just before going for full start. Have I got a problem or is this normal? Any idea's

Brake pump kicking in. Should stop after a few seconds. Perfectly normal.

Thanks. It does stop quite quick.

Good news, it means that the system is holding it's pressure.

+1 on that.

+1 on that, plus the blend motors will do a reset although you would need good hearing unless they are worn.

Not every time that you operate the ignition.
