Fuel Pump Relay

Fuel pump relay is mounted on right side of dashboard. Remove relay and check continuity. It should be present at terminals 1 and 2, and terminals 3 and 5.
With 12 volts applied to terminals 1 and 2, continuity should be present across terminals 3 and 5, but not at 3 and 6. If test is okay, check harness. If not okay, replace relay. See Fig 1.
