I think it's the fuel pump. I went to the library to get the Haynes book and it said to take of the left rear tire and listen when the key is turned to the "on" position. Well I did that and heard nothing at all. I didn't know what I was supposed to be listening for, so I got in my car and did the same thing and heard the"whirring". So I got back in hers and heard nothin. So I'm gonna start there. Anyone know about how much they run and how hard it is to put them in?
