INJECTOR REPLACEMENT
Use care in removing injectors to prev
ent damage to the electrical connector
pins on top of the injector, the fuel injector fuel filter and nozzle. The fuel injector
is serviced as a complete assembly on ly and should never be immersed in any
type of cleaner.
SINGLE INJECTOR UNITS 1. Relieve the fuel system pressure.
2. Remove the air cleaner.
3. Detach the injector connector by squeezing the two tabs together and
pulling straight up.
4. Remove the screws securing the fuel meter cover. Note the location of
any short screws for correct placement during reassembly.
CAUTION - DO NOT remove the four screws se curing the pressure regulator to
the fuel meter cover. The fuel pressure regulator includes a large spring under
heavy tension which could cause personal injury if released.
5. With the old fuel meter gasket in place to prevent damage to the casting,
use a prytool and fulcrum to pry the inje ctor carefully until it is free from
the fuel meter body.
6. Remove the injector.
7. Remove the large O-ring and steel back-up washer at the top of the
injector cavity in the fuel meter body.
8. Remove the small O-ring located at the bottom of the injector cavity.
To Install: 9. Lubricate the new, small O-ring with automatic transmission fluid; then,
push the new O-ring on the nozzle end of the injector up against the
injector fuel filter.
10. Install the steel backup washer in the recess of the fuel meter body.
Lubricate the new large O-ring with automatic transmission fluid, then
install the O-ring directly above t he backup washer, pressing the O-ring
down into the cavity recess. The O-ri ng is properly installed when it is
flush with the casting surface.
WARNING - Do not attempt to reverse this procedure and install the backup
washer and O-ring after the injector is located in the cavity. To do so will
prevent proper seating of the O-ring in th e cavity recess which could result in a
fuel leak and possible fire.
11. Install the injector by using a pushing/twisting mo tion to center the nozzle
O-ring in the bottom of the injector cavity and aligning the raised lug on
the injector base with the notch cast into the fuel meter body. Push down
on the injector making sure it is fully seated in the cavity. Injector
installation is correct when the lug is seated in the notch and the
electrical terminals are parallel to the throttle shaft.

The mass air flow systems measure the
mass of air that is drawn into the
engine cylinders, rather than just the vo lume. The sensor contains a hot-wire
sensing unit, which is made up of an electronic balanced bridge network.
Whenever current is suppli ed to the sensor, the bridge is energized and the
sensing hot-wire is heated. As the air enter s the mass air flow sensor, it passes
over and cools the hot wire. When the hot wire is cooled, it's resistance changes
and additional current is needed to k eep the bridge network balanced. This
increase in current is sent to the computer as a voltage signal and is used to
calculate the mass of the incoming air. The ECM uses this information to\

determine the duration of fuel injection pulse, ignition timing and EGR operation.
The speed density systems calculate the volume of air moving through the
intake. The ECM establishes the speed fact or through a signal from the ignition
module. The Manifold or Intake Air Temperature (MAT/IAT) and the Engine
Coolant Temperature (ECT) sensors work together to assure that proper
temperature information gets to the ECM wh ile the Manifold Absolute Pressure
(MAP) sensor monitors the changes in m anifold pressure which results from
changes in engine loading. These three se nsors contribute to the density factor.
Together, these inputs (engine speed, coolant temperature sensor, etc ...) are
the major determinants of the air/fuel mixture delivered by the fuel injection
system.
The following engines and fuel managem ent systems are covered in this
section:
• 1985-1989 2.8L MPFI - Mass Air Flow
• 1990-1992 3.1L MPFI - Speed Density
• 1985-1989 5.0L and 5.7L TPI - Mass Air Flow
• 1990-1992 5.0L and 5.7L TPI - Speed Density
Relieving Fuel System Pressure

1. Disconnect the negative battery cable to prevent fuel discharge if the key
is accidentally turned to the RUN position.
2. Loosen the fuel filler cap to reliev e the tank pressure and do not tighten
until service has been completed.
3. Connect J-34730-1 fuel pressure gauge or equivalent, to the fuel
pressure test valve. Wrap a shop towel around the fitting while
connecting the gauge to prevent spillage.
4. Place the end of the bleed hose into a suitable container and open the
valve to relieve the fuel system pressure.
ELECTRIC FUEL PUMP
REMOVAL & INSTALLATION
The fuel pump is part of t he fuel sender assembly located inside the fuel tank.

In addition to the above it
ems there are several others that are not absolutely
necessary, but handy to have around. These include an equivalent oil
absorbent gravel, like cat litter, and the usual supply of lubricants, antifreeze
and fluids. This is a basic list for rout ine maintenance, but only your personal
needs and desire can accurately determine your list of tools.
After performing a few projects on the vehi cle, you'll be amazed at the other
tools and non-tools on your workbench. Some useful household items are: a
large turkey baster or siphon, empty coff ee cans and ice trays (to store parts), a
ball of twine, electrical t ape for wiring, small rolls of colored tape for tagging
lines or hoses, markers and pens, a note pad, golf tees (for plugging vacuum
lines), metal coat hangers or a roll of mechanic's wire (to hold things out of the
way), dental pick or similar long, poi nted probe, a strong magnet, and a small
mirror (to see into rece sses and under manifolds).

The cooling system should be drained, th
oroughly flushed and refilled at least
every 30,000 miles or 24 months. This operation should be done with the \
engine cold.
1. Drain the cooling system as de scribed earlier in this section.
2. Fill the cooling system with warm water and start the engine. Run the
engine until normal operating temperature is reached.
3. At this point, turn the engine o ff and again drain the cooling system.
4. Repeat this procedure until the flui d draining from the system is nearly
colorless.
5. Remove, empty and reinstall the coolant recovery reservoir assembly.
6. Fill the cooling system with a 50/50 mixture of ethylene glycol antifreeze,
as outlined in the prev ious procedure.
BRAKE MASTER CYLINDER
FLUID RECOMMENDATIONS
When adding or replacing the brake fluid, always use a top quality fluid, such as
Delco Supreme II or equivalent DOT-3 flui d. DO NOT allow the master cylinder
reservoir to remain open for long periods of time; brake fluid absorbs moisture
from the air, reducing it s effectiveness and causing corrosion in the lines.
Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring cables
or electrical connections. Brake fl uid will damage paint and electrical
connections. If any fluid is spilled on t he vehicle, flush with water to lessen
damage.
LEVEL CHECK

Fig. 1: Check master cylinder fluid leve l against indicator on side of reservoir.
Fluid level should not be below MIN marking on reservoir.

1. Raise the car by the frame so that the rear axle can be independently
raised and lowered.
2. Support the rear axle with a floor jack.
3. If equipped with brake hose attaching brackets, disconnect the brackets
allowing the hoses to hang free. Do not disconnect the hoses. Perform
this step only if the hoses woul d otherwise be stretched and damaged
when the axle is lowered.
4. Disconnect the track bar from the axle.
5. Remove the lower shock absorber bol ts and lower the axle. Make sure
the axle is supported securely on t he floor jack and that there is no
chance of the axle slipping after the shock absorbers are disconnected.
On vehicles equipped with a 4-cylinder engine, remove the driveshaft.
6. Lower the axle and remove the coil spring. Do not lower the axle past th\
e limits of the brake lines or the lines will be damaged.

1. Jack up the car to a convenient working height. Support the axle
assembly with jackstands.
2. Disconnect the upper s hock attaching nuts.
3. Remove the lower shock to axle mounting bolt.
4. Remove the shock absorber.
To install: 5. Position the shock into place.
6. Install the lower shoc k to axle mounting bolt. Torque to 70 ft. lbs. (95
Nm).
7. Connect the upper shock attaching nuts. Torque the upper nuts to 13 ft.
lbs. (17 Nm).
8. Lower the car.
TESTING
Visually inspect the shock absorber. If there is evidence of leakage and the
shock absorber is covered with oil, t he shock is defective and should be
replaced.
If there is no sign of excessive leakage (a small amount of weeping is normal)
bounce the car at one corner by pressi ng down on the fender or bumper and
releasing. When you have the car bouncing as much as you can, release it. The
car should stop bouncing after the first rebound. If the bouncing continues past
the center point of the bounce more t han once, the shock absorbers are worn
and should be replaced.

9. Lower the vehicle.
CONTROL ARM
REMOVAL & INSTALLATION
Remove/reinstall only one lower control ar m at a time. If both arms are removed
at the same time, the axle could roll or slip sideways, making reinstallation of
the arms very difficult.
1. Raise the rear of the vehicle, pl ace jackstands under the rear axle, then
lower the jack so that the stands are supporting all of the weight.
2. Remove the control arm attachi ng fasteners, then remove the control
arm.

bolts at the body brace bracket to 35 ft. lbs. (47 Nm) and the nut at the
body bracket to 61 ft. lbs. (83 Nm).
TORQUE ARM
REMOVAL & INSTALLATION
The coil springs must be removed BEFORE the torque arm. If the torque arm is
removed first, vehicle damage will result. In order to proceed, the vehicle must
be supported in a manner whic h will allow the rear axle height to be adjusted
independently of the body height.
1. Remove the track bar mounting bolt at the axle assembly, then loosen
the track bar bolt at the body brace.
2. Disconnect the rear brake hose clip at the axle assembly, which will allow
additional drop of the axle.
3. Remove the lower attaching nuts from both rear shock absorbers.
