Fuel Injector: Service and Repair

REMOVAL

1. REMOVE AIR INTAKE CHAMBER
2. REMOVE FUEL PRESSURE PULSATION DAMPER
3. REMOVE DELIVERY PIPE AND INJECTORS

NOTICE:
- Be careful not to drop the injectors when removing the delivery pipe.
- Pay attention to put any hung load on the injector to and from the side direction.

(a) Disconnect these connectors:
- 6 injector connectors
- Camshaft position sensor connector
- Throttle position sensor connector
- VSV connector for EVAP





(b) Remove the 3 bolts and delivery pipe together with the 6 injectors.
(c) Pull out the 6 injectors from the delivery pipe.
(d) Remove the O-rings, grommet and insulator from each injector.
(e) Remove the 3 spacers from the intake manifold.

INSTALLATION

1. INSTALL INJECTORS AND DELIVERY PIPE





(a) Install new insulator and grommet to each injector.
(b) Apply a light coat of spindle oil or gasoline to 2 new O-rings and install them to each injector.
(c) Apply a light coat of spindle oil or gasoline on the place where a delivery pipe touches an O-ring of the injector.





(d) While turning the injector clockwise and counterclock wise, push it to the delivery pipe. Install the 6 injectors.
(e) Position the injector connector outward.
(f) Place the 3 spacers in position on the intake manifold.
(g) Apply a light coat of spindle oil or gasoline on the place where a intake manifold touches an O-ring of the injector.
(h) Place the 6 injectors together with the delivery pipe and 3 bolts in position on the intake manifold.
(i) Temporarily install the 3 bolts holding the delivery pipe to the intake manifold.
(j) 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.

(k) Position the injector connector upward.
(l) Connect the 6 injector connectors.

HINT: The Nos.1, 3, 5 injector connectors and dark gray, and the Nos.2, 4, 6 injector connectors are brown.

(m) Tighten the 3 bolts holding the delivery pipe to the intake manifold.

Torque: 21 N.m (210 kgf.cm, 15 ft.lbf)

(n) Connect these connectors:
- Camshaft position sensor connector
- Throttle position sensor connector
- VSV connector for EVAP
