(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.
(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 the following
procedures:
(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.

(b) When connecting the union bolt on the high pressure pipe
union, observe the following procedures:
(1) Always use 2 new gaskets.
(2) Tighten the union bolt by hand.
(3) Tighten the union bolt to the specified torque.

(c) When connecting the flare nut on the high pressure pipe
union, observe the following procedures:
(1) Apply a light coat of engine oil to the flare nut, and
tighten the flare nut by hand.
(2) Using SST, tighten the flare nut to specified torque.
SST 09023-12700
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque: 28 N´m (285 kgf´cm, 21 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(d) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O-ring.
(2) When placing a new O-ring on the injector, take
care not to damage it in any way.
(3) Coat a new O-ring with spindle oil or gasoline be-
fore installing-never use engine, gear or brake oil.
(e) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
(f) Observe these precautions when disconnecting the fuel
tube connector (quick type).
(1) Check if there is any dirt like mud on the pipe and
around the connector before disconnecting them
and clean the dirt away.
(2) Be sure to disconnect with hands.

INSPECTION
1. INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
(a) Disconnect the vapor pressure sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminals VC and E2 of the wiring harness side.
Voltage: 4.5 - 5.5 V
(d) Turn the ignition switch OFF.
(e) Reconnect the vapor pressure sensor connector.
2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the fuel hose from the vapor pressure sensor.
(c) Connect a voltmeter to terminals PTNK and E2 of the
ECM, and measure the output voltage under the following
conditions:
(1) Apply vacuum (2.0 kPa (15 mmHg, 0.59 in.Hg)) to
the vapor pressure sensor.
Voltage: 1.3 - 2.1 V
(2) Release the vacuum from the vapor pressure sen-
sor.
Voltage: 3.0 - 3.6 V
(3) Apply pressure (1.5 kPa (15 gf/cm
2, 0.22 psi)) to the
vapor pressure sensor.
Voltage: 4.2 - 4.8 V
(d) Turn the ignition switch OFF.
(e) Reconnect the fuel hose to the vapor pressure sensor.
