Remove fuel pump relay. See ELECTRICAL COMPONENT LOCATIONS table at beginning of article. Without voltage applied to relay, there should be no continuity between terminals No. 30 and 32, and between terminals No. 31 and 32. See Fig 1 . With battery voltage applied across terminals No. 28 and 29, there should be continuity between terminals No. 30 and 32, and between terminals No. 31 and 32. If continuity is not as specified, replace relay.
