To change the fuel pump on a 1984 Nissan 300ZX, first, disconnect the negative battery terminal and relieve fuel system pressure by removing the fuel cap and using a fuel pressure gauge. Next, access the fuel pump by removing the rear seat and the access panel. Disconnect the fuel lines and electrical connector from the pump, then unbolt the pump assembly and replace it with the new unit. Reassemble everything in reverse order, ensuring all connections are secure before reconnecting the battery.
