CHECKING THE INJECTORS
WARNING
EWA2S31037
• Check the injectors in a well-ventilated area
free of combustible materials. Make sure
that there is no smoking or use of electric
tools in the vicinity of the injectors.
• Be careful when disconnecting the fuel
hoses. Any remaining pressure in the fuel
hoses may cause the fuel to spray out.
Place a container or rag under the hoses to
catch any fuel that spills. Always clean up
any spilt fuel immediately.
• Turn the main switch to “OFF” and discon-
nect the negative battery lead from the bat-
tery terminal before checking the injectors.
NOTICE
ECA2S31076
• Always use new O-rings.
• When checking the injectors, do not allow
any foreign material to enter or adhere to
the injectors, fuel rail, or O-rings.
• Be careful not to twist or pinch the O-rings
when installing the injectors.
• If an injector is subject to strong shocks or
excessive force, replace it.
• If installing the original fuel rail and bolts,
remove the white paint marks using a
cleaning solvent. Otherwise, paint chips on
the bolt seats could prevent the bolts from
being tightened to the specified torque.
1. Check:
• Injectors

Replace.
Refer to “FUEL INJECTION SYSTEM” on
page 8-33.

INSTALLING THE INJECTORS
1. Install a seal onto the end of each injector.
2. Install the injectors to the injector joints.
3. Install the fuel rail, making sure to install them
in the correct direction.
4. Install the injector assemblies to the throttle
bodies.
5. Check the injector pressure after the injectors
are installed to the throttle bodies.
Refer to “CHECKING THE INJECTOR
PRESSURE” on page 7-14.

a. Connect the injector pressure adapter “1” to
the fuel rail “2”, and then connect an air com-
pressor “3” to the adapter.
b. Connect the pressure gauge “4” to the injec-
tor pressure adapter “1”.
c. Close the valve on the injector pressure
adapter.
d. Apply air pressure with the air compressor.
e. Open the valve on the injector pressure
adapter until the specified pressure is
reached.
NOTICE

Never exceed the specified air pressure or
damage could occur.
f. Close the valve on the injector pressure
adapter.
g. Check that the specified air pressure is held
for about one seconds.
