If the result is not as specified, replace the
injector.
(b) Inspect the injection volume.
CAUTION:
This test involves high-pressure fuel and
electricity. Take every precaution regarding safe
handling of both the fuel and the electricity.
Perform this test in a safe area, and avoid any
sparks or flames. Do not smoke.
(1) Install the fuel tube connector to SST (hose),
then connect the tube connector to the fuel
pipe (vehicle side).

41500)
(2) Install the O-ring to the fuel injector.
(3) Connect SST (adaptor and hose) to the
injector, and hold the injector and union with
SST (clamp).
SST 09268-41048 (09268-41130, 90467-
13001), 09268-41400
(4) Put the injector into the graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector
to contain gasoline spray.
(5) Operate the fuel pump.
(6) Connect SST (wire) to the injector and the
battery for 15 seconds, and measure the
injection volume with the graduated cylinder.
Test each injector 2 or 3 times.
SST 09842-30080
Standard volume:
84 to 100 cm
3 (5.1 to 6.0 cu in.) in 15
seconds
Difference between each injector:
16 cm
3 (0.96 cu in.) or less
If the injection volume is not as specified,
replace the injector.

(c) Check for leakage.
(1) In the condition above, disconnect the tester
probes of SST (wire) from the battery and
check for fuel leakage from the injector.
Fuel drop:
1 drop or less in 16 minutes
INSTALLATION
1. INSTALL FUEL INJECTOR ASSEMBLY
(a) Apply a light coat of spindle oil or gasoline to 6 new
O-rings, and install an O-ring to each injector.
(b) Apply a light coat of spindle oil or gasoline where
the fuel delivery pipe contacts the O-ring.
(c) Push the fuel injector while twisting it back and forth
to install it in the fuel delivery pipe.
(d) Position the fuel injector connector outward.
NOTICE:
• Be careful not to twist the O-ring.
• After installing the fuel injector, check that it
turns smoothly. If it does not, reinstall it with
a new O-ring.
(e) Install 6 new insulators to the intake manifold.
(f) Place the fuel delivery pipe together with the 6 fuel
injectors into the intake manifold.
NOTICE:
Be careful not to drop the fuel injectors when
installing the fuel delivery pipe.

(g) Temporarily install the 5 bolts which are used to hold
the fuel delivery pipe to the intake manifold.
NOTICE:
After installing the fuel injector, check that it
turns smoothly. If it does not, reinstall it with a
new O-ring.
(h) Tighten the 5 bolts which are used to hold the fuel
delivery pipe to the intake manifold.
Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf)
(i) Connect the 6 fuel injector connectors.
2. CONNECT FUEL MAIN TUBE
(a) Push in the tube connector to the pipe until the tube
connector makes a "click" sound.
NOTICE:
• Check that there is no damage or foreign
objects on the connected part of the fuel pipe.
• After connecting, check if the fuel tube
connector and the pipe are securely
connected by pulling on them.
(b) Install the No. 2 fuel pipe clamp.
3. INSTALL INTAKE AIR SURGE TANK ASSEMBLY (See
page EM-34)
4. INSTALL ENGINE ASSEMBLY
(a) Install the engine (see page EM-31).
5. ADD ENGINE COOLANT (See page CO-8)
6. CONNECT CABLE TO NEGATIVE BATTERY
TERMINAL
7. CHECK FOR ENGINE COOLANT LEAKS (See page
CO-1)
8. CHECK FOR FUEL LEAKS

ON-VEHICLE INSPECTION
1. CHECK FUEL CUT RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating
noise.
(c) Check that the operating sounds stop momentarily
and then resume when the throttle lever is released.
HINT:
Measure with the A/C OFF.
Fuel return rpm:
1,400 rpm
2. CHECK FOR LEAKS
(a) Visually check that the hoses, connections and
gaskets have no cracks, leaks or damage.
NOTICE:
• Detachment or other problems with the
engine oil dipstick, filler cap, PCV hose and
other components may cause the engine to
run improperly.
• Disconnection, looseness or cracks in the
parts of the air induction system between the
throttle body and cylinder head will allow air
suction and cause an engine failure or engine
malfunctions.
If the result is not as specified, replace parts as
necessary.
3. CHECK LINE AND CONNECTORS
(a) Visually check for loose connections, sharp bends
or damage.
4. CHECK FUEL TANK ASSEMBLY
(a) Visually check for deformation, cracks or fuel
leakage.
5. CHECK FUEL TANK AND VENT LINE
(a) Disconnect the vent line tube from the canister.
(b) Connect a pressure gauge to the vent line tube.
