Hello forum! I may have a slight problem. I tried searching, but it was really to no avail. The only thread I found was this one and it wasn't that helpful.
Fuel Pump?
Anyways, I have a very high pitched whine coming from behind the drivers seat (it's a very faint/hard to hear ringing). I thought it was the ECU but glove box is silent. I know its the fuel pump judging from the origin of the noise. It only happens when the car is running (Not in the ON position) and when the engine is cold and/or it's cold outside. There is even an audible and louder whine that can be heard standing behind the car even from a few a feet away. It will eventually go away after the car has been driven or it's warm outside.
Has anyone else experienced this? Is it normal for some of the 09s or do I need to get it replaced? I am having my mechanic look at it in a few weeks but I am antsy and need some peace of mind. Thanks for any input.
Also car starts with no problems, smooth idle, no RPM dip so the pump seems to be working fine.
