Timing Belt
Removal
Replace the timing belt at 105,000 miles (168,000 km)
according to the maintenance schedule {normal condi-
tions/severe conditions). lf the vehicle is regularly driven
in either of the following conditions, replace the timing
belt at 60,000 miles (U.S.A.l 100.000 km (Canada).
- ln very high temperatures (over 110'F, 43"C).- In very low temperatures (under -20"F. -29"C).
Turn the crankshaft pu\ley so the No. 1 piston is at
top dead center (TDC).
Remove the guard bar and splash shield (see page

Turn the ignition switch ON (ll), but do not operate the starter. After the fuel pump runs for approximately two seconds,
the fuef pressure in the fuel line rises. Repeat this two or three times, then check whether there is any fuel leakage.

Fuel Pump
Testing
lf you suspect a problem with the fuel pump, check that
the fuel pump actually runs; when it is oN (ll), you will
hear some noise if you hold your ear to the fuel fill port
with the fuel fill cap removed. The fuel pump should run
for two seconds when ignition switch is first turned ON (ll).
lf the fuel pump does not make noise, check it as follows:
1. Fold the left rear seat cushion forward, and remove
the base frame cover (see section 20).
2, Remove the access panel from the floor.
3. Make sure the ignition switch is OFF, then discon-
nect the fuel pumP 5P connector.
4. Connect the PGM-FI main relay 7P connector termr-
nal No. 4 and No, 5 with a jumper wire.

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.

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.
