If it blew a fuse chances are the pump is bad.You will need to lower the tank to check for power and ground while someone cranks the engine over.If you have power and ground replace the pump,strainer,fuel filter and the wiring harness that plugs in at the top of the tank.Failure to replace the harness will result in a repeat failure in most cases.
