(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (±) cables.
(c) Do not permit parts to receive a severe impact during re-
moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Be careful during troubleshooting as there are numerous
transistor circuit, and even slight terminal contact can
cause further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care should be taken when pulling out and inserting wir-
ing connectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) Use SST for inspection or test of the injector or its wiring
connector.

8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch to LOCK.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.

(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.

3. INSPECT THROTTLE OPENER
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed.
Idle speed: 700 ± 50 rpm
(c) Disconnect the vacuum hose from the throttle opener,
and plug the hose end.
(d) Check the throttle opener setting speed.
Throttle opener setting speed: 900 ± 1,950 rpm
If the throttle opener setting is not as specified, replace the
throttle body.
(e) Stop the engine.
(f) Reconnect the vacuum hose to the throttle opener.
(g) Start the engine and check that the idle speed returns to
the correct speed.

(c) After engine speed is kept at 900 ± 1,300 rpm for 10 se-
conds, check that it returns to idle speed.
(d) Stop the engine.
(e) Disconnect the air assist hose from the air pipe, and block
off the IAC valve exit and the entry to the pipe.
(f) Start the engine and check that the idle speed reaches
500 rpm or below (the engine may stall).
If the idle does not reach 500 rpm or below, check for a leak be-
tween the air assist hoses, pipe and injectors.
(g) Remove the SST from the DLC1.
