Okay so I've run into a problem, and this just happened out of nowhere. When I started my car today it just died immediately after. Also when you turn the key but, do not start the car, there's a noise that I believe is the fuel pump. Now I can normally hear it for just a few seconds, but today it just continued without stopping. Which leads me to believe that something is wrong with the fuel pump, but I'm not sure. Any ideas?
