ON−VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand−
held tester main switch ON.
NOTICE:
Do not start the engine.
(c) Select the active test mode on the TOYOTA hand−held
tester.
(d) Please refer to the TOYOTA hand−held tester operator’s
manual for further details.
(e) If you have no TOYOTA hand−held tester, connect the
positive (+) and negative (−) leads from the battery to the
fuel pump connector.
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check these parts:
H−fuse (ALT 80A)
M−fuses (AM1 40A, AM2 30A)
Fuses (EFI 15A, IGN 7.5A)
EFI main relay
Circuit opening relay
Fuel pump
ECM
Wiring connections
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand−held tester 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 6 bolts, and disconnect the No.2 timing belt
cover.
(d) Remove the union bolt holding the fuel pipe to the delivery
pipe and gasket.
CAUTION:
Put a shop towel under the delivery pipe. Slowly loosen the
union bolt.

2, 38 − 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check these parts:
Fuel hoses and connections
Fuel pump
Fuel filter

VSV for fuel pressure control
(k) Disconnect the TOYOTA hand−held tester from the
DLC3.
(l) Reinstall the No.2 timing belt cover with the 6 bolts.
(m) Start the engine.
(n) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator, and plug the hose end.
(o) Measure the fuel pressure at idle.
Fuel pressure:
265 − 304 kPa (2.7 − 3.1 kgf/cm
2, 38 − 44 psi)
(p) Reconnect the vacuum sensing hose to the fuel
pressure regulator.
(q) Measure the fuel pressure at idle.
Fuel pressure:
226 − 265 kPa (2.3 − 2.7 kgf/cm
2, 33 − 38 psi)
If pressure is not as specified, check the vacuum sensing hose
and fuel pressure regulator.
(r) Stop the engine.
(s) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:
147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(t) After checking fuel pressure, disconnect the negative (−)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
SST 09268−45012
(u) Remove the other union bolt, 3 gaskets and fuel pipe
from the delivery pipes.

(v) Reinstall the fuel pipe with 4 new gaskets and the 2 union
bolts.
Torque:34.3 N·m (350 kgf·cm, 25 ft·lbf)
(w) Reconnect the negative (−) terminal cable to the battery.
(x) Check for fuel leakage.

INSPECTION
1. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump and/
or set plate.
2. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 1 of
the connector, and the negative (−) lead to terminal 2. Check
that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds) to
prevent the coil from burning out.Keep the fuel pump as far
away from the battery as possible.Always do switching at
the battery side.
If operation is not as specified, replace the fuel pump and/or
plate.
