FUEL DELIVERY SYSTEM
FUEL PRESSURE INSPECTION
1) Relieve fuel pressure in fuel feed line referring to FUEL PRES-
SURE RELIEF PROCEDURE in SECTION 6.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel delivery pipe and
fuel feed hose (1) as shown in figure, and clamp hoses securely
to ensure no leaks occur during checking.
Special Tool
(A): 09912-58441
(B): 09912-58431
(C): 09912-58490
4) Check that battery voltage is above 11V.
WARNING:
Be sure to perform work in a well-ventilated area and
away from any open flames, or there is a risk of a fire
breaking out.
CAUTION:
A small amount of fuel may be released when fuel
hose is disconnected. Place container under the joint
with a shop cloth so that released fuel is caught in
container or absorbed in cloth. Place that cloth in an
approved container.
5) Turn ignition switch ON to operate fuel pump and after 2 se-
conds turn it OFF. Repeat this 3 or 4 times and then check fuel
pressure.
6) Start engine and warm it up to normal operating temperature.
7) Measure fuel pressure at idling.
If measured pressure doesn’t satisfy specification, refer to B-3
FUEL PRESSURE CHECK in this section and check each
possibly defective part. Replace if found defective.

8) After checking fuel pressure, remove fuel pressure gauge.
CAUTION:
As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following
procedures.
Place fuel container under joint.
Cover joint with rag and loosen joint nut slowly to
release fuel pressure gradually.
