Test D: Fuel Gage Accuracy Test

Disconnect Fuel Tank Unit connector C409 and connect the two red clip leads of tester J-33431 to terminals B (PPL) and D (BLK/WHT) of the harness half of that connector. With the Ignition Switch in RUN, set the resistance dial on the tester to 0 ohms (E), 44 ohms (1/2), and 90 ohms (F).

^ If the Fuel Gage responds correctly, and all wiring and connections are OK, install a new Fuel Gage Sender.
^ If the Fuel Gage does not respond correctly, check PPL (30) and BLK/WHT (803) wires for high resistance. Also check the Instrument Cluster connections and screws at the back of the cluster. They should be clean and tight. If all checks are OK, replace the Instrument Cluster.
