Special Tools Required Adjustable ring wrench 07WAA-0010100 NOTE: For the fuel gauge system circuit diagram, refer to the Gauges Circuit Diagram (see page 22-88). Check the No. 10 METER (75A) fuse in the under-dash fuse/relay box before testing. Turn the ignition switch OFF. Remove the rear seat cushion (see page 20-237). Remove the access panel from the floor. Disconnect the fuel pump 5P connector. Measure voltage between the fuel pump 5P connector terminals No. 1 and No. 2 with the ignition switch ON (II). There should be between 5 and 8 V. If the voltage is as specified, go to step 7. If the voltage is not as specified, check for: an open in the YEL/BLK or BLK wire. poor ground (G551). FUEL PUMP 5P CONNECTOR Wire side of female terminals

Turn the ignition switch OFF. Install a 2 ohm; resistor between the fuel pump 5P connector terminals No. 1 and No. 2, then turn the ignition switch ON (II). FUEL PUMP 5P CONNECTOR Wire side of female terminals Check that the pointer of the fuel gauge indicates ''F''. If the pointer of the fuel gauge does not indicate ''F'', replace the gauge. If the gauge is OK, inspect the fuel gauge sending unit. NOTE: The pointer of the fuel gauge returns to the bottom on the gauge dial when the ignition switch is OFF regardless of the fuel level.
