FUEL DELIVERY SYSTEM
FUEL PRESSURE INSPECTION
1) Relieve fuel pressure in fuel feed line referring to p. 6-4.
2) Using backup wrench, loosen plug bolt on fuel delivery pipe and
remove it. Connect special tools (fuel pressure gauge) to deliv-
ery pipe.
CAUTION:
A small amount of fuel may be released when plug bolt
is loosened. Place container under the bolt or cover bolt
hole with a shop cloth so that released fuel is caught in
container or absorbed in cloth. Place that cloth in an ap-
proved container.
Special Tool
(A): 09912-58441
(B): 09912-58431

3) Check that battery voltage is above 11V.
4) Turn ignition switch ON to operate fuel pump and after 3 seconds
turn it OFF. Repeat this 3 or 4 times and then check fuel pres-
sure.
5) Start engine.
6) Measure fuel pressure at idling.
If measured pressure doesn’t satisfy specification, refer to
“Diagnostic Flow Table B-3” in “ENGINE DIAGNOSIS” section
and check each possibly defective part. Replace if found defec-
tive.
7) 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.
