Dash Unit Dead Between Empty and Full with Ignition "ON"

Disconnect tank unit feed wire. Using a voltmeter, check feed wire voltage for 3-4 volts. If correct, connect gas gauge tester (J-22344) to tank unit feed wire and observe dash unit. If still dead, remove dash unit and check. If voltage does not register on meter, it indicates an open circuit on HOT side of dash unit. Check cluster fuse, connections at printed circuits for both dash unit and panel harness. If circuits okay, remove dash unit and check.
