When ever I start the engine I hear a high-pitched noise that sounds like some sort of electrical interference somewhat like a noisy old home computer. The noise does not stop until I turn off the car. Does anyone have this issue. Would a grounding kit help? Thanks for your input.

Can you locate the source of the noise? I don't have that sound coming from the speakers, but I have a different sound from the engine bay when warming her up. It only happens in extremely cold weather, and I figure it's just moving parts. It goes away after 15 seconds or so.

Fuel pump?, Leaky Vacuum line?

I have heard this noise for a while now too, but only if my stock sub location hatch is opened.

I believe it is the fuel pump, I believe it generates a frequency only audible to certain person(s). i.e. people who can hear in that spectrum, It's a common thing. My fathers computer monitor used to annoy the sh*t of me growing up, only I was the only one that could hear it.
