The fuel pump relay fuse will be labeled "ECM B" in the under hood fuse box.

Your fuel pump is probably out. But it chould be a blown fuse, or a bad connection at the fuel pump module?

Try tapping the bottem of the tank with a rubber mallet....if it starts the carbon brushes are bad in the fuel pump.
