Do you have power at the fuel pump connector? If no power you have a open in the wire between the module and the pump. Look at the harness carefully, sometimes mice chew electrical wires. Also check the wires resistance between the module and pump. Have you checked the fuel pump relay and the fuse?

Try running your own ground with scrap piece of wire and see if the pump runs.
