2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of
SST (wire) from the battery and check the fuel leakage
from the injector.
SST 09842±30070
Fuel drop: One drop or less per minute
(b) Disconnect the battery negative (±) cable.
(c) Remove SST.
SST 09268±41045 and 09843±18020 (k) Connect SST (wire) to the injector and battery for 15
seconds, and measure the injection volume with a
graduated cylinder. Test each injector two or three
times.
SST 09842±30070 .
Volume: 45 ± 55 cc (2.7 ± 3.4 cu in.) per 15 sec.
Difference between each injector:
5 cc (0.3 cu in.) or less
If the injection volume is not as specified, replace the injec-
tor.

(e) Place the three injectors together with the RH delivery
pipe and No.1 fuel pipe in position on the intake man-
ifold.
(f) Place the three injectors together with the LH delivery
pipe in position on the intake manifold.
(g) Check that the injectors rotate smoothly.
HINT: If injectors do not rotate smoothly, the probable
cause is incorrect installation of 0±rings. Replace the
O±rings.
(h) Position the injector connector upward.
