(l) Connect SST (wire) to the injector and battery for 15
seconds, and measure the injection volume with a
graduated cylinder. Test each injector 2 or 3 times.
SST 09842±30070
Volume:
49 ± 59 cm
(3.0±3.6 cu in.) per 15 sec.
Difference between each Injector:
5 cm
(0.3 cu in.) or less
If the injection volume is not as specified, replace the
injector.
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 negative (±) terminal cable from the
battery. SST 09268±41045 (09268±41080)

link connector 1.
SST 09843±18020
(j) Reconnect the negative (±) terminal cable to the
battery.

(i) Check that the injectors rotate smoothly.
HINT: If injectors do not rotate smoothly, the probable
cause is incorrect installation of O ± rings. Replace the
O±rings.
(j) Position the injector connector upward.
(l) Connect the fuel return hose.
(m) Connect the fuel inlet pipe to the delivery pipe with 2
new gaskets and the pulsation damper.
Torque: 34 N±m (350 kgf±cm, 25 ft±lbf)
(k) Tighten the 2 bolts holding the delivery pipe to the
cylinder head.
Torque: 13 N±m (130 kgf±cm, 9 ft±lbf)
3. INSTALL INTAKE MANIFOLD
(a) Connect the 2 wire clamps to the wire brackets
on the intake manifold. 2. CONNECT INJECTOR CONNECTORS

FUEL LINES AND CONNECTIONS
INSPECTION
(a) Check the fuel lines for cracks, leakage and all con±
nections for deformation.
(b) Check the fuel tank vapor vent system hoses and
connections for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leak±
age and tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and tube connections are as shown in the illus±
tration.
If a problem is found, repair or replace the part as
necessary.
PRECAUTIONS
1. Always use new gaskets when replacing the fuel
tank or component parts.
2. Apply the proper torque to all parts tightened.

2. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Disconnect the sensor connector.
(c) Insert a thickness gauge between the throttle stop
screw and stop lever.

C. Check and adjust throttle opener setting speed
(a) Disconnect the vacuum hose from the throttle opener,
and plug the hose end.
(b) Maintain the engine at 2,500 rpm.
(c) Release the throttle valve.
(d) Check that the throttle opener is set.
Throttle opener setting speed:
1,300 ± 1,500 rpm (w/ Cooling fan OFF) (d) Using an ohmmeter, measure the resistance between
each terminal.
(e) Reconnect the sensor connector.
