Fuel Pump Relay/Main Relay

NOTE: Both fuel pump and main relays are identical. Following test procedures apply to both.
  1. Turn ignition off. Disconnect negative battery cable. Disconnect relay connector and remove relay. See Fig 1-Fig 4 for location. Using an ohmmeter, check continuity between terminals "A" and "B". See Fig 5. If continuity is not present, go to next step. If continuity is present, replace relay.
  2. Check resistance between terminals "C" and "D". If resistance is 70-110 ohms (79-95 on Vitara 1.6L and 2.0L), go to next step. If resistance is not as specified, replace relay.
  3. Energize relay by applying battery voltage and ground to terminals "C" and "D". Check continuity between terminals "A" and "B". If continuity is present, relay is okay. If continuity is not present, replace relay.
