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.
Slowly loosen the 12 mm banjo bolt one complete
rurn 12 mm BANJoBOLT

SHOP TOWEL
NOTE: Replace the washers whenever the 12 mm
banio bolt is loosened or removed.

Inspection
1, Relieve fuel pressure.
2. Remove the 12 mm banjo bolt on the fuel filter while
holding the fuel filter with another wrench. Attach
the 12 mm fuel pressure adapter bolt and the special
tool.
FUEL PRESSUREREGULATON

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:

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.

1. Attach the special tool and the 12 mm fuel pressure
adapter bolt to the fuel filter (see page 1l-178)
2. Start the engine.

lf the fuel pressure did not rise, replace the fuel
pressure regulator.

Replacement
'1. Place a shop towel under the fuel pressure regula-
