(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, 09268-45014
(g) Wipe off any splattered gasoline.
(h) Reconnect the TOYOTA hand-held tester to the DLC3
(See step 1).
(i) Reconnect the negative (-) terminal cable to the battery.
(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 hose clamp to the fuel filter with ºclickº
sound.
(s) After installing the clamp, check that the clamp is fixed by
pulling up to the clamp.
(t) Reconnect the negative (-) terminal cable to the battery.
(u) Check for fuel leaks.
3. REMOVE REAR SEAT CUSHION
4. REMOVE FLOOR SERVICE HOLE COVER
5. DISCONNECT FUEL PUMP & SENDER GAUGE CON-
NECTOR
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.
