Q: Hum/whining noise

asked by on

There is a hum/whining noise at the back of the car.

Hello. The hum/ whining noise you hear might be your fuel pump. If you turn your key to the run position without starting the car, and you hear the same noise for about five seconds, that could be your fuel pump. Typically, when fuel pumps get that loud, they are on the path to failure. It would be wise to have it replaced before it fails. If the noise is something different, you will need the aid of mechanic to isolate the whining noise for a proper diagnosis.
