Fuel Pump Relay Inspection (Millenia 2.5L, Protege, Protege5 & 626)

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.
