Did anyone ever gone through this... a humming sound coming from inside cabin and a vibration on the rear passenger seat whenever i turn my key to start the engine... no problem on starting the engine and the sound will die away after it starts..if i try to turn off engine and restart, there is no sound.. very hard to get the sound after driving to the mech.. hav to wait till engine cool enough to get the sound againfuel pump about to die?? my car is 520 m54b22
