WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure for 110-150 ohms of resistance between terminals 1 and 2 of the fuel pump relay.
    • if the resistance is not within the specified range, replace the fuel pump relay.
  2. Measure for infinite resistance between the following terminals of the fuel pump relay:
    • 3 and 2
    • 3 and 5
    • 3 and 1
    • 1 and 5
    • if continuity is detected, replace the fuel pump relay.
  3. Connect a 15 amp fused jumper wire from the positive terminal of the battery to relay terminal 1. Connect a jumper wire from the negative terminal of the battery to relay terminal 2. Measure for less than 2 ohms between terminals 3 and 5 of the relay.
    • if the resistance measures more than 2 ohms, replace the fuel pump relay.
