The Standard Ignition Fuel Pump Relay RY-664 is a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1994-1997 Mazda Miata, 1996 Mazda MPV and 1992-1996 Mazda MX-3. See the "Vehicles it fits" section for the full list and engine details.
A fuel pump relay is an electrically operated switch. When the control circuit energizes it, the relay closes and sends power to the electric fuel pump, so the pump runs only when commanded. If a failed relay is the cause of a crank-but-no-start, a pump that does not prime at key-on, or intermittent stalling, this unit replaces it. Those symptoms can have other causes, so diagnose the fuel system before replacing parts.
