ON±VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect a 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. (See step 7)
(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:
Fusible link
Fuses
EFI main relay
Fuel pump
ECM
Wiring connections
(g) Turn the ignition switch OFF.
(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) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.

(d) Remove the fuel hose clamp.
(e) Disconnect the No.1 fuel pipe (fuel tube connector) from
the fuel filter outlet.
CAUTION:
Perform disconnecting operations of the fuel tube
connector (quick type) after observing the precau-
tions. (See page SF±1)
As there is retained pressure in the fuel pipe line, pre-
vent it from splashing inside the engine compart-
ment.
(f) Install SST (pressure gauge) as shown in the illustration
by using SST and fuel tube connector.
SST 09268±41047, 09268±41250, 09268±45012
(g) Wipe off any splattered gasoline.
(h) Reconnect the negative (±) terminal cable to the battery.
(i) Connect the TOYOTA hand held tester to the DLC3.
(See step 1. check fuel pump operation (a) to (e))
(j) Measure the fuel pressure.
Fuel pressure:
301 ± 347 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 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
Fuel pressure regulator
(k) Disconnect the TOYOTA hand±held tester from the
DLC3.
(l) Start the engine.
(m) Measure the fuel pressure at idle.
Fuel pressure:
301 ± 347 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
(n) Stop the engine.
(o) 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.

(quick type) after observing the precautions.
(See page SF±1)
(r) Surely install the fuel hose clamp to the fuel filter with
ºclickº sound.
(s) After installing the clamp, check that the clamp is fixed by
pulling up the clamp.

6. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
4 and 5.
Resistance: 0.2 ± 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
7. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 4 of
the connector, and the negative (±) lead to terminal 5. Check
that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.
Keep the fuel pump as far away from the battery as
possible.
Always do the switching at the battery side.
