Your fuel pump relay is located on the firewall passenger side.
Under the hood in the fuse/relay module.
A vehicle has many relays: Starter, Horn, Blower motor, wiper, Headlight, Fuel pump, etc.
The 1994 Ford Mustang fuel pump relay switch is located below the fuel injector pump. The relay switch should be labeled as such.
In the trunk, under the carpet, behind the driver's side brake light.
there should be a fuse box located in the engine compartment, remove the lid on this box and the location of the relay should be on the inside of the lid, you should have a least 3 or 4 relays along with fuses in this box, your fuel pump relay and fuse are there.
