Quick whining noise when shutting down car? (Sometimes when unlocking doors)

AlphaSnacks · 09-11-2011, 07:35 PM

I've noticed a new sound over the past month, a quick whine that sounds from somewhere around the passengers's side when I shut down the car - sounds for about half a second. I also just noticed it when I hit the unlock button twice on my keyfob (car was off) and it did it then.

I know fuel pumps can whine when they engage and disengage, but it's odd to me that I've never noticed the sound before - because it is very obvious and perceptible, definitely not faint. I'd have noticed something like that from the first day of owning the car. I also know this isn't the ECU whine, because it mostly happens when the car turns off and it sounds like it's coming from the passengers side somewhere.

Where is the fuel pump located on our cars?
