2008 RRS HSE V8
On occasion after turning the engine off, removing the key and exiting the vehicle I hear a pump or motor running sound from somewhere near the rear axle passanger side (Right Side). It runs for about 30 seconds then goes off. It’s definitely not coming from the air compressor.
My only guess is that it sounds like the fuel pump running but why would the fuel pump run with the engine off and key out of the ignition?
