RELIEVING FUEL SYSTEM PRESSURE
1. Remove the fuse marked "Fuel Pu mp" from the fuse block in the
passenger compartment.
2. Crank the engine. Th e engine will start and run until the fuel supply
remaining in the lines is exhauste d. When the engines stops, engage the
starter again for three seconds to a ssure dissipation of any remaining
pressure.
3. With the ignition OFF, disconnect the negative battery cable to prevent
fuel discharge if the key is accidentally turned to the ON position.
Replace the fuse with the ignition OFF.
When disconnecting fuel lines, there ma y still be a small amount of fuel
released. Cover the fuel line connection wi th a shop cloth to collect the fuel,
then place the cloth in an approved container.
ELECTRIC FUEL PUMP
REMOVAL & INSTALLATION
The removal and installation procedures fo r the Crossfire injection system fuel
pump is identical to the Throttle Body In jection (TBI) system. Please refer to the
TBI fuel pump procedures earlier in this repair guide.
TESTING
The testing procedures for the Crossfire in jection system fuel pump is identical
to the Throttle Body Injection (TBI) syst em. Please refer to the TBI fuel pump
procedures earlier in this repair guide.
THROTTLE BODY
REMOVAL & INSTALLATION
FRONT UNIT
1. Relieve the fuel system pressure.
2. Remove the air cleaner assembly, noting the connection points of the
vacuum lines.
3. Detach the electrical connectors at the injector and the idle air control
motor.
4. Disconnect the vacuum lines from the TBI unit, noting the connection
points. During installation, refer to the underhood emission control
information decal for vacuum line routing information.
5. Disconnect the transmission det ent cable from the TBI unit.
6. Disconnect the fuel inlet (feed) and fuel balance line connections at the
front TBI unit.
7. Remove and discard the throttle cont rol rod retaining clip from the front
TBI throttle lever stud. A new clip must be used during reassembly.
8. Unbolt and remove the TBI unit.

To install:
9. Replacement of the manifold cover or either throttle body requires throttle
valve synchronizing and checking of the throttle rod alignment (see
"Preliminary Adjustments"). Before installing the replacement throttle
body unit(s) on the engine, perform the following steps:
a. If the tamper resistant plugs co vering the throttle stop screws are
in place, remove the plugs.
b. If the front TBI unit throttle syn chronizing screw has a welded
retaining collar, grind off the weld.
c. Block possible movement of the throttle lever, relieving the force
of the heavy spring against the throttle synchronizing screw. This
prevents the levers from coming into contact.
If the lever is not blocked before the thro ttle synchronizing screw is removed,
the screw may be damaged, and reinstallation will be accomplished only with
great difficulty.
d. Remove the synchronizing screw and collar. Discard the collar and reinstall the screw. The blocking from the throttle lever (installed in the
previous step) can now be removed.
CAUTION - The collar must be removed to prevent possible interference with
the air cleaner. Failure to do so c ould result in personal injury
10. Use new gaskets and tighten the TB I bolts to 120-168 inch lbs. (13-19
Nm) during installation.
11. Perform the preliminary adjustm ents. These procedures must be
followed before further assembly.
12. Reconnect the fuel lines to the TBI units. Use a backup wrench to
prevent the nuts from tu rning in the TBI unit.
13. Reconnect the throttle cable and detent cable.
14. Reconnect all related vacuum lines.
15. Reconnect the electrical connectors.
16. With the engine OFF, depress the accelerator pedal to the floor and
release. Check for free return of the pedal.
17. Check the throttle position sensor voltage and adjust if necessary.
18. Perform the Minimum Idle and Thro ttle Valve Synchronization adjustment
procedures.
Rear Unit 1. Relieve the fuel system pressure.
2. Remove the air cleaner assembly, noting the connection points of the
vacuum lines.
3. Disconnect the electrical connectors at the injector, idle air control motor,
and throttle position sensor.
4. Disconnect the vacuum lines from the TBI unit, noting the connection
points. During installation, refer to the underhood emission control
information decal for vacuum line routing information.

BODY LUBRICATION
HOOD LATCH AND HINGES
Clean the latch surfaces and
apply clean engine oil to the latch pilot bolts and
the spring anchor. Use the engine oil to l ubricate the hood hinges as well. Use a
chassis grease to lubricate all the pivot points in the latch release mechanism.
DOOR HINGES
The gas tank filler door, car door, and rear hatch or trunk lid hinges should be
wiped clean and lubricated with clean engi ne oil. Silicone spray also works well
on seals, but must be applied more often. Use engine oil to lubricate the trunk
or hatch lock mechanism and the lock bo lt and striker. The door lock cylinders
can be lubricated easily with a shot of silicone spray or one of the many dry
penetrating lubricants commercially available.
PARKING BRAKE LINKAGE
Use chassis grease on the parking brake c able where it contacts the guides,
links, levers, and pulleys. The grease s hould be water resistant for durability.
ACCELERATOR LINKAGE
Lubricate the throttle lever, and the accele rator pedal lever at the support inside
the car with clean engine oil.
TRANSMISSION SHIFT LINKAGE
Lubricate the shift linkage with water re sistant chassis grease which meets GM
Specification 6031M or its equal.
FRONT WHEEL BEARINGS
Once every 30,000 miles, clean and repack wheel bearings with a wheel
bearing packer. Remove any excess grea se from the exposed surface of the
hub and seal.
REMOVAL, REPACKING, INSTA LLATION AND ADJUSTMENT
WARNING - It is important that wheel b earings be properly adjusted after
installation. Improperly adj usted wheel bearings can c ause steering instability,
front end shimmy and wander, and increased tire wear.
1. Raise the car and support it at the lower arm. Remove the tire and wheel
assembly.
2. Remove the brake caliper and support it on a wire.
3. Remove the dust cap, cotter pin, ca stle nut, thrust washer and outside
wheel bearing.
4. Pull the disc/hub assembly from the steering knuckle.
