drop the gas tank...pull the fuel mod out and replace the pump
pull out the bottom part of the back seat, under which will reveal a hatch that lets you get to the fuel pump.
its in the boot, pull the trunk carpet and it should be covered in some weird black foam tape.
In a 1987 Nissan 200SX, the fuel pump relay is typically located in the engine compartment, near the fuse box. It may be mounted on the fender or on the firewall. For specific identification, consult the vehicle's service manual or wiring diagram, as the exact location can vary.
The fuel pump is locate inside the fuel tank. By removing the rear seat from the vehicle, you will see the access cover of the fuel pump. Now you just have to disconected the fuel line and some screws to be able to lift the fule pump out.
in the fuel tank
Drop the fuel tank.
i laik to remuve the fuel pump
In the 1984 Nissan 200SX, the fuel pump relay is typically located in the engine compartment, near the fuse box on the driver's side. It may be mounted on the inner fender or near the firewall. Refer to the vehicle's service manual for specific diagrams and exact locations, as configurations can vary slightly based on the model and engine type.
I believe that on these cars the entire electric fuel pump assembly is a single unit under the back seat with a metal plate that covers it.
Take off the sockets and remove the pump pulley.
remove fuel tank and remove fuel pump where the fuel line go into the tank cover and pump is in side of tank
