Fuel Tube/Ouick-Gonnect Fittings
Procautions
@ Do not smoke whils working on the fuel
syst6m, Koop open flames away from your work ar9a.
The fuel tube/quick-connect fittings assembly connects
the in-tank fuel pump with the fuel feed pipe. For remov-
ing or installing the fuel pump and fuel tank, it is neces-
sary to disconnect or connect the quick-connect fittings.
Pay attention to following;
. The fuel tube/quick-connect fittings assembly is not
heat-resistant; be careful not to damage it during weld-
ing or other heat-generating procedures.
. The fuel tube/quick-connect fittings assembly is not
acid-proof; do not touch it with a shop towel which
was used for wiping battery electrolyte. R€place the
fuel tube/quick-connect fittings assembly if it came
into contact with electrolyte or somethino similar.
. When connecting or disconnecting the fuel tube/quick-
connect fittings assembly, be careful not to bend or
twist it excessively, Replace it if damaged,
A disconnected quick-connect fittings can be reconnected,
but the retainer on the mating pipe cannot be reused once
it has been removed from the pipe. Replace tha retainer

Fuel Supply System
System Description
The fuel supply system consists of a fuel tank, in-tank
high-pressure fuel pump. PGM-Fl main relay, fuel filter,
fuel pressure regulator, fuel injectors, and fuel delivery
and return lines. This system delivers pressure-regulat-
ed fuel to the fuel injectors and cuts the fuel delivery
when the engine is not running.
Fuel Pressure
Relieving
Before disconnecting fuel pipes or hoses, release pres-
sure from the system by loosening the 12 mm banjo
bolt on the too of the fuel filter.
Do not smoke while working on the fuel system.
Ke€p open flames or sparks away from your work
area,
Be sure to relieve fuel pressure while the ignition
switch is off.
Write down the frequencies for the radio's preset
buttons.
Disconnect the battery negative cable from the bat-
tery negative terminal.
Remove the fuel fill cap.
Use a box end wrench on the 12 mm banjo bolt at
the fuel filter while holding the fuel filter with anoth-
er wrench.
Place a rag or shop towel over the '12 mm banjo bolt.

The illustration shows'97 - 98 models,'99 - 00 models are similar.
Start the engine. Measure the fuel pressure with the
engine idling and the vacuum hose of the fuel pres-
sure regulator disconnected from the fuel pressure
regulator and pinched. lf the engine will not start,
turn the ignition switch on (ll), wait for two seconds,
turn it off, then back on again and read the fuel
pressure.
Pressure should be:'97 - 98 mod€ls:
260 -31O kPa 12.7 - 3.2 kgf/cm,, 38 - 46 psil'99 - 0O models:

lf the fuel pressure is not as specified, first check the
fuel pump (see page 11- 183). lf the fuel pump is OK,
check the following:
. lf the fuel pressure is higher than specified,
inspect for:- Pinched or clogged fuel return hose or line.- Faulty fuel pressure regulator (see page 11-
181).
. lf the fuel pressure is lower than specified. inspect
for:- Clogged fuel filter.- Faulty fuel pressure regulator (see page 11-
1811.- Fuel line leakage.

Fuel Pump
Testing
lf you suspect a problem with the fuel pump, check that
the fuel pump actually runs; when it is oN (ll), you will
hear some noise if you hold your ear to the fuel fill port
with the fuel fill cap removed. The fuel pump should run
for two seconds when ignition switch is first turned ON (ll).
lf the fuel pump does not make noise, check it as follows:
1. Fold the left rear seat cushion forward, and remove
the base frame cover (see section 20).
2, Remove the access panel from the floor.
3. Make sure the ignition switch is OFF, then discon-
nect the fuel pumP 5P connector.
4. Connect the PGM-FI main relay 7P connector termr-
nal No. 4 and No, 5 with a jumper wire.

PGM-FI Main Relay
Description
The PGM-Fl main relav actuallv contains two individual
relays. This relay is located at the passenger side of the
cowl. One relay is energized whenever the ignition is on
which supplies the battery voltage to the ECM/PCM,
power to the fuel injectors, and power for the second
relay. The second relay is energized for two seconds
when the ignition is switched on, and when the engine
is running, to supply power to the fuel pump

NOTE: lf the engine starts and continues to run, the
PGM-FI main relay is OK.

board lower cover (see section 20).
2. Remove the PGM-FI main relay
3. Aftach the battery positive terminal to the No. 2 ter-
