normal mounting position.
1. Lightly lubricate fuel injector O-rings with clean
engine oil.
2. Push retaining clip onto fuel injector, aligning clip as
shown.
3. Press fuel injector into fuel injector cap until retaining
clip snaps into place.
4. Press fuel injector into bore in intake manifold and
rotate to original position.
5. Install fuel injector cap screw into intake manifold
and torque to 7.3 N·m (65 in. lb.).
6. Push electrical connector on fuel injector making
sure a good connection is made.
7. Repeat steps 1 through 6 for other fuel injector.
Install Manifold Absolute Pressure (MAP) Sensor or
Temperature/Manifold Absolute Pressure (TMAP)
Sensor (ECV EFI)
NOTE: Ensure all parts are clean, undamaged and free
of debris and make sure electrical connector has
seal in place.
1. Lightly oil MAP or TMAP sensor O-ring and push
sensor into bore in intake manifold.
2. Torque screw to 7.3 N·m (65 in. lb.).
3. Push electrical connector on MAP or TMAP sensor
making sure a good connection is made.
Install Crankshaft Position Sensor
NOTE: Ensure all parts are clean, undamaged and free
of debris and make sure electrical connectors
have seal in place.
NOTE: On engines with earlier design bracket, an air
gap must be set when installing. Later design
brackets require no adjustment.
1. Install crankshaft position sensor and bracket
assembly to crankcase posts.
2. On engines with earlier design bracket, snug screws
and check air gap of sensor with a feeler gauge. It
must be 0.20-0.70 mm (0.008-0.027 in.). Torque
bracket screws to 8.3 N·m (73 in. lb.).
On engines with later design bracket, secure bracket
assembly to crankcase posts. Torque bracket screws
to 7.3 N·m (65 in. lb.).
3. Push electrical connector on crankshaft position
sensor making sure a good connection is made.
