2009 AWD humming when key on

Post by Mustbefamousjr »

Today I noticed a pretty intense humming sound when I turned the key to the ON position without starting the engine. I don't believe it's the fuel pump because that usually shuts off after a second or two. This humming/buzzing sound stays going and sounds like it's coming from the top of the engine somewhere. Anyone have any ideas, is this normal for vibes?
