(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to a new O−ring and install
it to the injector.
(c) While turning the injector left and right, install it to the de-
livery pipe. Install the 4 injectors.
(d) Position the injector connector upward.

6. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc.,
first disconnect the power by either turning the ignition
switch OFF or disconnecting the negative (−) terminal
cable from the battery.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (−) terminal cable from the battery.
(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 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.
(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) When inspecting a connector with a volt/ohmmeter
(1) Carefully take out the water−proofing rubber if it is
a water−proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water−proofing rubber on
the connector securely.
(5) Use SST for inspection or test of the injector or its
wiring connector.

REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will result
in the removal of natural fats from the skin, leading to dry-
ness, irritation and dermatitis. In addition, used engine oil
contains potentially harmful contaminants which may
cause skin cancer. Care should be taken, therefore, when
changing engine, oil to minimize the frequency and length
of time your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil should
be worn. The skin should be thoroughly washed with soap
and water, or use water−less hand cleaner, to remove any
used engine oil. Do not use gasoline, thinners, or solvents.
In order to preserve the environment, used oil and used oil
filters must be disposed of only at designated disposal
sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter.
SST 09228−07501
(b) Check and clean the oil filter installation surface.
(c) Apply clean engine oil to the gasket of a new oil filter.
(d) Lightly screw the oil filter into place, and tighten it until the
gasket contacts the seat.
(e) Using SST, tighten it an additional 3/4 turn.
