- 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 the 6 injector connectors.
b. Disconnect the camshaft position sensor connector.
c. Disconnect the throttle position sensor connector.
d. Disconnect the VSV connector for EVAP.




e. Remove the 3 bolts and delivery pipe together with the 6 injectors.
f. Pull out the 6 injectors from the delivery pipe.
g. Remove the O-rings, grommet and insulator from each injector.
h. 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 counterclockwise, 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.
