(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN-8).
Cancel the parking brake on the level place and
shift the transmission in N position.
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks. It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission-related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step-down
adapter for adjustment. Once the hose has been
stretched, it may leak air.

ON-VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect a TOYOTA hand-held tester or OBD II scan tool
to the DLC3.
(b) Turn the ignition switch ON, and press the TOYOTA
hand-held tester or OBD II scan tool main switch ON.
NOTICE:
Do not start the engine.
(c) Select the ACTIVE TEST mode on the TOYOTA hand-
held tester or OBD II scan tool.
(d) Please refer to the TOYOTA hand-held tester or OBD II
scan tool operator's manual for further details.
(e) If you have no TOYOTA hand-held tester or OBD II scan
tool, connect the positive (+) and negative (-) leads from
the battery to the fuel pump connector. (See step 3)
(f) Disconnect the fuel return hose from the clamp on the V-
bank cover.
(g) Remove the 2 bolts, nuts and V-bank cover.
(h) Check that the pulsation damper screw pop up when the
fuel pump operates.
If operation is not as specified, check following parts:

Fusible link

Fuses

EFI main relay

Fuel pump

ECM

Wiring connections
(i) Turn the ignition switch OFF.
(j) Disconnect the TOYOTA hand-held tester or OBD II scan
tool from the DLC3.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is above 12 V.
(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Remove the front fuel pipe from the LH delivery pipe (See
page SF-22).
(d) Install the front fuel pipe and SST (pressure gauge) to the
delivery pipe with the 3 lower gaskets and SST (adaptor).

Torque: 39 N´m (400 kgf´cm, 29 ft´lbf)
(e) Wipe off any splattered gasoline.
(f) Reconnect the negative (-) terminal cable to the battery.
(g) Connect a TOYOTA hand-held tester or OBD II scan tool
to the DLC3 (See (a) to (e) in step 1 on the check fuel
pump operation).
(h) Measure the fuel pressure.
