ENGINE GENERAL INFORMATION AND DIAGNOSIS (TBI FOR G10) 6-5
FUEL PRESSURE RELIEF PROCEDURE
CAUTION:
This work must not be done when engine is hot. If done so,
it may cause adverse effect to catalyst.
After making sure that engine is cold, release fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (Shift selector le-
ver to “P” range for A / T model), set parking brake, and block
drive wheels.
2) Remove relay box cover.
3) Disconnect fuel pump relay (1) from relay box (2).
4) Remove fuel filler cap to release fuel vapor pressure in fuel tank
and then reinstall it.
5) Start engine and run it till it stops for lack of fuel. Repeat cranking
engine 2-3 times for about 3 seconds each time to dissipate fuel
pressure in lines. Fuel connections are now safe for servicing.
6) Upon completion of servicing, connect fuel pump relay to relay
box and install relay box cover.
FUEL LEAKAGE CHECK PROCEDURE
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 2 seconds (to operate fuel pump) and
then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pressure
to fuel line. (till fuel pressure is felt by hand placed on fuel feed
hose.)
2) In this state, check to see that there are no fuel leakages from
any part of fuel system.

REMOVAL
1) Release fuel pressure in fuel feed line by referring to Section
6.
2) Remove battery.
3) Remove engine hood after disconnecting windshield washer
hose.
4) Drain cooling system.
WARNING:
To help avoid danger of being burned, do not remove
drain plug (2) and radiator cap while engine and radiator
(1) are still hot. Scalding fluid and steam can be blown
out under pressure if plug and cap are taken off too
soon.
5) Disconnect coupler of cooling fan motor.
6) Disconnect radiator inlet hose from thermostat case.
7) Disconnect A / T fluid hoses from A / T fluid pipes (for A / T mod-
el)
8) Remove outlet hose from water inlet pipe and radiator.
9) Remove radiator referring to Section 6B.
10) Remove air cleaner case and air cleaner outlet hose as pre-
viously outlined.
11) Disconnect the following cables.

Accelerator cable (1) from throttle body.

A / T throttle pressure control cable from A / T.
