This cold weather lately has made me notice something. A super high pitch tone coming from the back of my 2011 370Z Sport Touring. The amp for the Bose system is back there, and the fuel pump. Only things I could think of. It does it regardless of the radio being turned on or off, but doesn't do it unless the engine has started, so I think it's the fuel pump. Doesn't do it when the temp is 40 or higher, only notice it when leaving work late at night and it's around 30 degrees or colder. It also stops by the time I'm home. Could it be that the fuel pump is just COLD and making that noise? Anybody else notice this or have had experience with this???
