INSPECTION
1) Disconnect fuel feed hose (1) from fuel feed pipe.
CAUTION:
A small amount of fuel may be released when fuel feed
hose is removed. Place container under the fuel feed
hose or fuel feed pipe with a shop cloth so that released
fuel is caught in container or absorbed in cloth. Place
that cloth in an approved container.
2) Connect special tools and hose (2) between fuel feed hose and
fuel feed pipe as shown in figure, and clamp hose securely to en-
sure no leaks occur during checking.

3) Check that battery voltage is above 11 V.
4) Turn ignition switch ON to operate fuel pump and after 5 seconds
turn it OFF. Repeat this 6 times and then check fuel pressure.
5) Start engine.
6) Measure fuel pressure at idling.
If measure pressure doesn’t satisfy specification, refer to “Diag-
nostic Flow Table B-2” in Section 6 and check each possibly de-
fective part. Replace if found defective.
7) After checking fuel pressure, remove special tools and hose
from fuel feed pipe.
8) Connect fuel feed hose and clamp it securely.
9) With engine “OFF” and ignition switch “ON”, check for fuel leaks.
