Fuel Gauge Indicates Full At All Times (Dual Tanks)
- Disconnect IPC connector. Install a fused jumper wire between IPC connector terminal No. 31 (Black wire) and ground. Install another fused jumper wire between IPC terminal No. 22 (Pink wire) and voltage. Install another fused jumper wire between IPC terminal No. 16 (Purple wire) and ground. If fuel gauge indicates full, replace IPC. If fuel gauge does not indicate full, go to next step.
- Remove fused jumper wires from IPC. Reconnect IPC connector. Disconnect fuel pump balance module connector. Connect fused jumper wire between fuel pump balance module connector terminal "F" (Purple wire) and ground. If fuel gauge indicates full, repair open circuit in Purple wire. If fuel gauge indicates empty, reconnect fuel pump balance module connector. Go to FUEL GAUGE INACCURATE (DUAL TANKS) test.
