(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) Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal con-
tact 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 is required when pulling out and inserting wiring con-
nectors.
(i) Release the lock and pull out the connector, pulling on the
connectors.
(j) Fully insert the connector and check that it is locked.
(k) Use SST for inspection or test of the injector or its wiring
connector.

(d) Check that there are no fuel leaks after performing main-
tenance anywhere on the fuel system.
(1) Connect the TOYOTA hand−held tester to the
DLC3.
(2) Turn the ignition switch ON and TOYOTA hand−
held tester main switch ON.

ator ’s manual for further details.
(5) If you have no TOYOTA hand−held tester, connect
the positive (+) and negative (−) leads from the bat-
tery to the fuel pump connector (See page
SF−5).
(6) Pinch the fuel inlet hose.
The pressure in the high pressure line will rise to
approx. 400 kPa (4 kgf/cm
2, 57 psi). In this state,
check that there are no leaks from any part of the
fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(7) Turn the ignition switch to LOCK.
(8) Disconnect the TOYOTA hand−held tester from the
DLC3.
(9) Start the engine.

If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check the H−fuse, fuses, EFI main relay,
circuit opening relay, fuel pump, ECM and wiring connections.
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand−held tester from the
DLC3.
2. CHECK FUEL PRESSURE

(b) Disconnect the negative (−) terminal cable from the bat-
tery.
(c) Remove the air cleaner assembly (See page ST−4).
(d) Remove the 2 bolts, and disconnect the engine comport-
ment R/B No.2 from the bracket on the body.
(e) Remove the union bolt and 2 gaskets, and disconnect the

ON−VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is normal operating noise
in proportion to engine speed.
(2) If you have no sound scope, you can check the in-
jector transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Remove the cylinder head cover (See page EM−33).
(b) Disconnect the injector connectors.
(c) Using an ohmmeter, measure the resistance between the
terminals.
Resistance: Approx. 13.8 Ω
If the resistance is not as specified, replace the injector.
