Fuel Pump Relay Inspection (Millenia 2.5L, Protege, Protege5 & 626)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
Remove fuel pump relay. See FUEL PUMP RELAY LOCATIONS table. Using ohmmeter, check for continuity between relay terminals "C" and "D" (terminals "B" and "E" on 626). See Fig 1 and Fig 2 . Continuity should not be present. Using fused jumper wires, connect positive battery terminal to fuel pump relay terminal "A". Connect negative battery terminal to fuel pump relay terminal "B" (terminal "F" on 626). Continuity should be present between fuel pump relay terminals "C" and "D" (terminals "B" and "E" on 626). If continuity is not as specified, replace fuel pump relay.
