Many turbocharger failures are due to oil supply
problems. Heat soak after hot shutdown can cause
the engine oil in the turbocharger and oil lines to
“coke.” Often the oil feed lines will become partially
or completely blocked with hardened particles of car-
bon, blocking oil flow. Check the oil feed pipe and oil
return line for cloggrng. Clean these tubes well. Al-
ways use new gaskets above and below the oil feed
eyebolt fitting. Do not allow particles of dirt or old
gasket material to enter the oil passage hole and that
no portion of the new gasket blocks the passage.
1. Disconnect the negative battery cable.
2. Drain the engine oil, cooling system and re-
move the radiator On vehicles equipped with A/C,
remove the condenser fan assembly with the radiator.
The EPA warns that prolonged contact with
used engine oil may cause a number of skin
disorders, including cancer! You should
make every effort to minimize your exposure
to used engine oil. Protective gloves should
be worn when changing the oil. Wash your
hands and any other exposed skin areas as
soon as possible after exposure to used en-
gine oil. Soap and water, or waterless hand
cleaner should be used.
Never open, service or drain the radiator or
cooling system when hot; serious burns can
occur from the steam and hot coolant. Also,
when draining engine coolant, keep in mind
that cats and dogs are attracted to ethylene Fig. 75 Exploded view

Observe all applicable safety precautions
when working around fuel. Whenever servic-
ing the fuel system, always work in a well
ventilated area. Do not allow fuel spray or
vapors to come in contact with a spark or
open flame. Keep a dry chemical fire extin-
guisher near the work area. Always keep fuel
in a container specifically designed for fuel
storage; also, always properly seal fuel con-
tainers to avoid the possibility of fire or ex-
plosion.
6. Disconnect the fuel return hose and remove
the O-ring.
7. Disconnect the vacuum hose from the fuel
pressure regulator.
8. Detach the electrical connectors from each
injector.
9. Remove the fuel pipe connectmg the fuel
rails. Remove the injector rail retaining bolts. Make
sure the rubber mounting bushings do not get lost.
10. Lift the rail assemblies up and away from the
engine.
11. Remove the injectors from the rail by pulling
gently. Discard the lower insulator.
To install:
*Some of the vehicles may have a clip that
secures the injector to the fuel rail. Be sure
to remove or install the injector clip where
necessary.
12. Install a new grommet and O-ring to the in-
jector. Coat the O-ring with light oil.
13. Install the injector to the fuel rail.
14. Replace the seats in the intake manifold. In-
stall the fuel rails and injectors to the manifold. Make
sure the rubber bushings are in place before tighten-
ing the mounting bolts.
15. Tighten the retaining bolts to 7-9 ft. Ibs.

18. Replace the O-ring, lightly lubricate it and
connect the high pressure fuel line.
19. Usmg new gaskets, install the intake plenum
and all related items. Refer to Section 3.
20. Fill the cooling system.
21. Connect the negative battery cable and check
the entire system for proper operation and leaks.
The easiest way to test the operation of the fuel in-
jectors is to listen for a clicking sound coming from
the injectors while the engine IS running. This is ac-
complished using a mechanic’s stethoscope, or a
long screwdriver. Place the end of the stethoscope or
the screwdriver (tip end, not handle) onto the body of
the injector. Place the ear pieces of the stethoscope
in your ears, or if using a screwdriver, place your ear
on top of the handle. An audible chcking noise
should be heard; this is the solenoid operating. If the
injector makes this noise, the injector driver circuit
and computer are operating as designed. Continue
testing all the injectors this way.
Be extremely careful while working on an op-
erating engine, make sure you have no dan-
gling jewelry, extremely loose clothes,
power tool cords or other items that might
get caught in a moving part of the ermine.
All Injectors Clicking
If all the injectors are clicking, but you have de-
termined that the fuel system is the cause of your
driveability problem, continue diagnostics. Make
sure that you have checked fuel pump pressure as
outlined earlier in this section. An easy way to de-
termine a weak or unproductive cylinder is a cylin-
der drop test. This is accomplished by removing
one spark plug wire at a time, and seeing which cylinder causes the least difference in the idle.
The one that causes the least change is the weak
cylinder.
If the injectors were all clicking and the ignition
system is functioning properly, remove the injector of
the suspect cylinder and bench test it. This is accom-
plished by checking for a spray pattern from the in-
jector itself Install a fuel supply line to the injector
(or rail if the injector is left attached to the rail) and
momentarily apply 12 volts DC and a ground to the
injector itself; a visible fuel spray should appear. If no
spray is achieved, replace the injector and check the
running condition of the engine.
One or More Injectors Are Not Clicking
6 See Figures 33, 34, 35, and 36
If one or more injectors are found to be not operat-
ing, testing the injector driver circuit and computer
can be accomplished using a “noid” light. First, with
the engine not running and the ignition key in the
OFF position, remove the connector from the injector
you plan to test, then plug the “noid” light tool into
the injector connector. Start the engine and the
“noid” light should flash, signaling that the injector
driver circuit is working. If the “noid” light flashes,
but the injector does not click when plugged in, test
the injectors resistance. Resistance should be be-
tween:
l All non-turbo engines: 13-16 ohms at 68°F
(20°C)
l Turbocharged engines: 2-3 ohms at 68 “F
(20°C)
If the “noid” light does not flash, the injector dri-
ver circuit is faulty. Disconnect the negative battery
cable. Unplug the “noid” light from the injector con-
nector and also unplug the PCM. Check the harness
between the appropriate pins on the harness side of
the PCM connector and the injector connector. Re-
sistance should be less than 5.0 ohms; if not, repair
the circuit. If resistance
IS within specifications, the
injector driver inside the PCM is faulty and replace-
ment of the PCM will be necessary.

REMOVAL &INSTALLATION
# See Figures 1, 2, 3, and 4
1. Park the vehicle on a level surface.
2. Remove the jack, tire iron and, if necessary,
the spare tire from their storage compartments.
3. Check the owners manual, or refer to Section
1 of this manual for the jacking points on your vehi-
cle. Then, place the jack in the proper position,
4. If equipped with lug nut trim caps, remove
them by either unscrewing or pulling them off the lug
nuts, as appropriate. Consult the owners manual, if
necessary.
5. If equipped with a wheel cover or hub cap,
insert the tapered end of the tire iron in the groove
and pry off the cover.
6. Apply the parking brake and block the diago-
nally opposite wheel with a wheel chock or two.
*Wheel chocks may be purchased at your
local auto parts store, or a block of wood cut
into wedges may be used. If possible, keep
one or two of the chocks in your tire storage
compartment, in case any of the tires has to
be removed on the side of the road. 7. If equipped with an automatic
transmission/transaxle, place the selector lever in P
or Park; with a manual transmission/transaxle, place
the shifter in Reverse.
8. With the tires still on the ground, use the tire
iron/wrench to break the lug nuts loose.
*If a nut is stuck, never use heat to loosen it
or damage to the wheel and bearings may
occur. If the nuts are seized, one or two
heavy hammer blows directly on the end of
the bolt usually loosens the rust. Be careful,
as continued pounding will likely damage the
brake drum or rotor.
9. Using the jack, raise the vehicle until the tire
is clear of the ground. Support the vehicle safely us-
ing jackstands.
10. Remove the lug nuts, then remove the tire
and wheel assembly.
To install:
11. Make sure the wheel and hub mating sur-
faces, as well as the wheel lug studs, are clean and
free of all foreign material. Always remove rust from
the wheel mounting surface and the brake rotor or
drum. Failure to do so may cause the lug nuts to
loosen in service.
12. Install the tire and wheel assembly and hand-
tighten the lug nuts. 13. Using the tire wrench, tighten all the lug nuts,
in a crisscross pattern, until they are snug.
14. Raise the vehicle and withdraw the jackstand,
then lower the vehicle.
15. Using a torque wrench, tighten the lug nuts in
a crisscross pattern to 65-80 ft. lbs. ( 90-l 10 Nm).
Check your owners manual or refer to Section 1 of
this manual for the proper tightening sequence.
Do not overtighten the lug nuts, as this may
cause the wheel studs to stretch or the brake
disc (rotor) to warp.
16. If so equipped, install the wheel cover or hub
cap. Make sure the valve stem protrudes through the
proper opening before tapping the wheel cover into
position.
17. If equipped, install the lug nut trim caps by
pushing them or screwing them on, as applicable.
18. Remove the jack from under the vehicle, and
place the jack and tire iron/wrench in their storage
compartments. Remove the wheel chock(s).
19. If you have removed a flat or damaged tire,
place it in the storage compartment of the vehicle and
take it to your local repair station to have it fixed or
replaced as soon as possible.
Inspect the tires for lacerations, puncture marks,
nails and other sharp objects. Repair or replace as
necessary. Also check the tires for treadwear and air
pressure as outlined in Section 1 of this manual.
Check the wheel assemblies for dents, cracks, rust
and metal fatigue. Repair or replace as necessary.
