NOTE: Refer to section 23 for the fuel gauge system cir-cuit diagram.
'1. Check the No. 25 METER (7.5 A) fuse in the under-dash fuse/relay box before testing.
2. Fold the left rear seat cushion forward, and remove
the base frame cover {see section 20).
3. Remove the access panel from the floor.
4. Disconnect the 5P connector from the fuel pump.
5. Measure voltage between the 5P connector termi-nals No.2 and No. 5 with the ignition switch ON ( ).There should be between 5 and 8 V.

7.
Turn the ignition switch OFF.
Attach a jumper wire between the No. 2 and No. 5terminals, then turn the ignition switch ON fll).
Check that the pointer of the fuel gauge starts mov-ing toward the "F" mark. Turn the ignition switchOFF before the pointer reaches "F" on the gauge
dial. Failure to do so may damage the luel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type,hence the fuel level is continuously indicated evenwhen the ignition switch is OFF, and the pointer
moves more slowly than that of a bimetal type.
. lf the pointer of the fuel gauge does not move atall. replace the gauge.
. lf the gauge is OK, inspect the fuel gauge send-ing unit.
