Millenia 2.3L

WARNING: This page is about a different car, the 2001 Mazda Protege, 2001 Mazda Millenia, 2001 Mazda MX-5 Miata, 2001 Mazda MPV, and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
  1. Fuel pump resistor and relay (speed) is located in left rear corner of engine compartment. Disconnect fuel pump resistor and relay connector. To check fuel pump resistor, measure resistance between relay terminals "A" and "B". See Fig 1 . Resistance should be .38-.42 ohm. If resistance is not as specified, replace fuel pump resistor and relay.
  2. To check relay, check for continuity between terminals "E" and "F". See Fig 1 . Continuity should not be present. Using fused jumper wires, apply battery voltage to connector terminals "C" and "D". Continuity should be present between terminals "E" and "F". If continuity is not as specified, replace fuel pump resistor and relay (speed).
