(d)Check that the fuel injectors rotate smoothly.
If the fuel injectors do not rotate smoothly, the probable cause
is incorrect installation of O±ring. Replace with the O±ring.
(e)Tighten the 2 bolts. Torque: 20 N

INSPECTION
1.INSPECT FUEL INJECTOR ASSY
(a)Inspect injector resistance (1)Using an ohmmeter, measure the resistance be-tween the terminals.
Resistance: 13.4 to 14.2 at 20
C (68
F)
If the resistance is not as specified, replace the injector.
(b)Inspect injector inspection
CAUTION:
This test involves high±pressure fuel and electricity. Take
every precaution regarding safe handling of both the fuel
and the electricity. Preform this test in a safe area, and
avoid any sparks or flame. Do not smoke.
(1)Obtain new No. 1 fuel pipe (part No. 23901±0H040)and remove the fuel tube connector from the pipe.
(2)Install the fuel tube connector to SST (hose), then connect the tube connector and the fuel pipe.
SST09268±41047 (95336±08070)
CAUTION:
Connect the fuel tube connector (quick type) after observ-
ing the precautions to prevent fuel from spraying.
(3)Install the O±ring to the injector.
(4)Connect SST (union and hose) to the injector, andhold the injector and the union with SST (clamp)
SST09268±41047 (09268±41110, 09268±41300, 95336±08070)
(5)Put the injector into a graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector to contain gas-
oline spray. (6)Operate the fuel pump.(See Page 11±19)

(7) Connect SST (wire) to the injector and the battery
for 15 seconds, and measure the injection volume
with a graduated cylinder. Test each injector 2 or 3
times.
SST 09842±30080
Injection volume:
Injection volumeDifference between each injector
60 to 73 cm3
(3.6 to 4.5 cu in.)
in 15 seconds13 cm3 (0.9 cu in.) or less
NOTICE:
Always do the switching at the battery side.
If the injection volume is not as specified, replace the injector.
(c) Inspect leakage
(1) In the condition above, disconnect the test probes
of SST (wire) from the battery and check the fuel
leakage from the injector.
Fuel drop: 1 drop or less in 12 minutes
2. INSPECT FUEL PUMP
(a) Insect fuel pump resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance: 0.2 to 3.0
at 20C (68F)
(b) Inspect fuel pump operation
(1) Apply battery voltage to both the terminals. Check
that the pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent damage to the pump.

Keep fuel pump as far away from the battery as pos-
sible.

Always do the switching at the battery side.

O±ring which seals the pipe and connector that can
be contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a vinyl or plastic bag.

When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
