Well just like the title says. I've never heard the damn sound prolly because the pump is under the seat but today I took out all of the interior and went to Toyota Dealership to get some parts, while driving I heard buzzing sound from the back of my car everytime I got over bumps. So while driving I started to kinda move the fuel pump wires side to side to see if its a short but that didn't do anything. SO then while stopped I started to bump on the fuel pump cover and everythying I bump on it the damn thing makes a buzzing noice.
So I was wondering if any of you have this kind of problem and if this is I should worry about.
