INSPECTION
1. REMOVE SECOND SEATS
2. REMOVE SCUFF PLATE
3. REMOVE SIDE GARNISH
4. REMOVE STEP PLATE
5. DISCONNECT FLOOR MATS
6. REMOVE FLOOR SERVICE HOLE COVER
Remove the 3 screws and service hole cover.
7. DISCONNECT FUEL PUMP AND SENDER GAUGE CONNECTOR
8. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals 5 and 6. Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
9. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 6 of
the connector, and the negative ( −) lead to terminal 5. Check
that the fuel pump operates.
NOTICE:
These tests must be performed quickly (within 10 se-
conds) to prevent the coil from burning out.
Keep the fuel pump as far away from the battery as
possible.
Always perform switching at the battery side.
If operation is not as specified, replace the fuel pump.

SFI INJECTOR
1996 LAND CRUISER (RM451U)
(f) Install the grommet and O−ring to the injector.
(g) Connect SST (union and hose) to the injector, and hold
the injector and union with SST (clamp).
SST 09268−41046
(h) Put the injector into the graduated cylinder.
HINT:
Install a suitable vinyl hose onto the injector to prevent gasoline
from splashing out.
(i) Remove the fuse cover on the instrument panel.
(j) Connect the TOYOTA hand−held tester to the DLC3.
(k) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(l) Select the active test mode on the TOYOTA hand −held
tester.
(m) Please refer to the TOYOTA hand −held tester operator’s
manual for further details.
(n) If you have no TOYOTA hand−held tester, connect the positive (+) and negative (−) leads from the battery to the
fuel pump connector (See page SF−14)
(o) Connect SST (wire) to the injector and battery for 15 se- conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842−30070
Volume:
69 − 88 cm
3 (4.2 − 5.4 cu in.) per 15 seconds
Difference between each injector:
5 cm
3 (0.3 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from
the injector.
SST 09842−30070
Fuel drop: One drop or less per minute
(b) Turn the ignition switch to LOCK.
(c) Disconnect the negative ( −) terminal cable from the bat-
tery.

FUEL PUMP RELAY
INSPECTION
1. REMOVE FUEL PUMP RELAY
(a) Disconnect the fuel pump relay connector.
(b) Remove the bolt and fuel pump relay.
2. INSPECT FUEL PUMP RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals +B1 and FPR.
(b) Check that there is continuity between terminals +B2 and
FP.
(c) Check that there is no continuity between terminals +B2
and PR.
If continuity is not as specified, replace the relay.
3. INSPECT FUEL PUMP RELAY OPERATION
(a) Apply battery voltage across terminals +B1 and FPR.
(b) Using an ohmmeter, check that there is no continuity be- tween the +B2 and FP.
(c) Check that there is continuity between terminals +B2 and
PR.
If operation is not as specified, replace the relay.
4. REINSTALL FUEL PUMP RELAY
