FUEL PRESSURE RELIEF PROCEDURE
After making sure that engine is cold, relieve fuel pressure as fol-
lows.
1) Shift transmission gear shift lever to “Neutral” position (shift se-
lector lever to “P” range for A / T vehicle), set parking brake, and
block drive wheels.
2) Remove fuel pump relay (1) from fuse/relay box (2).
3) Remove fuel filler cap to release fuel vapor pressure in fuel tank
and then reinstall it.
4) Start engine and run it till it stops for lack of fuel. Repeat crank-
ing engine 2 – 3 times, for about 3 seconds each time to dissi-
pate fuel pressure in lines. Fuel system (line) is now safe for
servicing.
5) Upon completion of servicing, install fuel pump relay (1) to fuse/
relay box (2).
CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.

FUEL LEAKAGE CHECK PROCEDURE
After performing any service on fuel system, check to make sure
that there is no fuel leakage as follows.
1) Turn ignition switch to ON position for 3 seconds (to operate fuel
pump) and then turn it to OFF position.
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 return
hose).
2) In this state, check to see that there is no fuel leakage from any
part of fuel system.
