MULTIPORT FUEL INJECTION
Grommet
Fuel rail
O-ring
REMOVAL SERVICE POINT
(A, HIGH PRESSURE FUEL HOSE DISCONNECTION
Bleed the residual pressure within the fuel pipe line so as
to prevent the flow of fuel.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
INSTALLATION SERVICE POINTS
(1) Apply a small amount of new engine oil to the O-ring.
Caution
Do not let the engine oil get into the fuel rail.
(2) While turning the injector to the left and right, install it
to the fuel rail.
(3) Check to be sure that the injector turns smoothly. If it
does not turn smoothly, the O-ring may be trapped, remove
the injector and then reinsert it into the fuel rail and check
again.
(1) Apply a small amount of new engine oil to a new O-ring
and insert it to the fuel rail carefully.
Caution
Do not let the engine oil get into the fuel rail.
(2) If the fuel pressure regulator does not move smoothly,
the O-ring may be folded. Then, remove the regulator
to check the O-ring for damage.
(3) Tighten the regulator to the specified torque.
Tightening torque: 9 Nm (7 ftlbs.)
CONNECTION
Apply a small amount of new engine oil to the fuel pipe and
high pressure fuel hose union, and then insert, being careful
not to damage the O-ring.
Caution
Do not let the engine oil get into the fuel rail.
INSPECTION
INJECTORS CHECK
(1) Measure resistance between terminals of injector using
a circuit tester.
Standard value:
13-16 Q [at 20°C (68"F)] <Non Turbo>
2-3 R [at 20°C (SSOF)] <Turbo>
(2) If the resistance is out of specification, replace the injector.
