PRECAUTIONS
._
1. Before working on the fuel system, disconnect the
negative terminal from the battery.
NOTE: Any diagnosis code retained by the computer will
be erased when the battery terminal is removed.
Therefore, if necessary, read the diagnosis before
removimg the battery terminal.
2. Do not smoke or work near an open flame when work-
ing on the fuel system.
3. Keep gasoline off rubber or leather parts.
INSPECTION PRECAUTl.ONS
MAINTENANCE PRECAUTIONS
1. INSURE CORRECT ENGINE TUNE-UP
2. PRECAUTIONS WHEN CONNECTING GAUGE
(a) Connect the tachometer test probe to the terminal
IGO of check connector.
CHECK CONNECTOR LOCATION:
See pages FI-110, 111
(b) Use the battery as the power source for the timing
light, tachometer, etc.
3. IN EVENT OF ENGINE MISFIRE FOLLOWING
PRECAUTIONS SHOULD BE TAKEN
(a) Insure proper connection of battery terminals, etc.
(b) Handle high tension cords carefully.
(c) After repair work, insure that the ignition coil ter-
minals and all other ignition system lines are recon-
nected securely.
(d) When cleaning the engine compartment, be especial-
ly careful to protect the electrical system from water.
4. PRECAUTIONS WHEN HANDLING OXYGEN SENSOR
(w/ TWCI
(a) Do not allow oxygen sensor to drop or hit against an
object.
(b) Do not allow water to come into contact with the
sensor or attempt to cool it.

INSPECT FUEL PUMP OPERATION
(a) Turn the ignition switch to ON. :
NOTE: Do not start the engine.
(b) Using a service wire, short circuit the fuel pump
check terminals +B and FP of the check connector.
CHECK CONNECTOR LOCATION:
See pages FI-1 10, 111
(c) Check that there is pressure in the fuel return hose.
NOTE: At this time, you will hear fuel pressure noise.
(d) Remove the service wire.
(el Turn the ignition switch OFF.
If there is no pressure, check the following parts.
i Fusible links
0 Fuse
0 EFI main relay
0 Fuel pump
0 Wiring connections
2. INSPECT FUEL PRESSURE
(a) Check that battery voltage is above 11 bolts.
(b) Disconnect the cable from the negative (-) terminal
of the battery.
(c) Remove the cold start injector tube.
(7M-GE)
0 Disconnect the wiring connector from the cold
start injector.

2. INSTALL FUEL PUMP FILTER TO FUEL PUMP
(a) Install’the pump filter with the clip.
(b) install the rubber cushion.
INSTALL FUEL PUMP TO FUEL PUMP BRACKET
(a) Insert the outlet port of the fuel pump into the fuel
hose.
(b) Push the lower side of the fuel pump and install the
fuel pump.
3. INSTALL FUEL PUMP BRACKET
Install a new gasket and the pump bracket with the
screws.
Torque: 35 kg-cm (30 in-lb, 3.4 N-m)
4.
INSTALL FUEL TANK
(a) Apply a thin coat of oil to the flare and tighten the
flare nut.
(b) Then using SST, tighten the nut to the specified tor-
que.

CAUTION:
l Tighten the fuel tank mounting bolts, etc. to the
specified torque.
l Tighten ‘the pipe union and flare nut (hose) to the
specified torque.
l Push in the pipe and insert-type hose to the
specified position, and install the clip to the
specified location.
l If reusing the hose, reinstall the clip at the original
location,

Do not leave the ignition switch on for more than 10
minutes if the engine does not start.
When a tachometer is connected to the system; con-
nect the tachometer test probe to the check connector
terminal IG 0 .
CHECK CONNECTOR LOCATION:
See pages FI-110, 111
As some tachometers are not compatible with this
ignition system, we recommended that you confirm
the compatibility of your unit before using.
NEVER allow the tachometer terminals to touch
ground as it could result in damage to the igniter and/
or ignition coil.
Do not disconnect the battery while the engine is run-
ning.
Make sure that the igniter is properly grounded to the
body.
