FUEL PRESSURE RELEASE
1.FUEL PRESSURE RELEASE
With CONSULT
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEA SE” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
Without CONSULT
1. Remove fuel pump fuse located in IPDM E/R. For the fuse number, refer to EC-117, "Wiring Diagram"
. For
the fuse arrangement, refer to PG-72, "Fuse, Connector and Terminal Arrangement"
.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK
CAUTION:
Before disconnecting fuel line, release fuel pr essure from fuel line to eliminate danger.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because th is models do not have fuel return system.
• Use Fuel Pressure Gauge Kit [SST: (J-44321)] to check fuel pressure.
1.FUEL PRESSURE CHECK
1. Release fuel pressure to zero.
2. Connect fuel tube adapter [SST:KV10120000] (B) to quick con-
nector.
3. Turn ignition switch ON and check for fuel leakage.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK FUEL HOSES AND FUEL TUBES
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES >> Replace “fuel filter and fuel pump assembly”. Refer to FL-6, "Removal and Installation".
NO >> Repair or replace error-detected parts.
A : Fuel pressure gauge
C : Fuel feed hose
: Vehicle front
At idling : Approximately 350 kPa (3.57 kg/cm2, 51 psi)
