1. Relieve the fuel system pressure as described
in this section.
2. Disconnect the PCV hose from the valve
cover. Also disconnect the breather hose at the oppo-
site end of the valve cover.
3. Remove the bolts holding the high pressure
fuel line to the fuel rail and disconnect the line. Be
prepared to contain fuel spillage; plug the line to
keep out dirt and debris.
Observe all applicable safety precautions
when working around fuel. Whenever servic-
ing the fuel system, always work in a well
ventilated area. 00 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.
4. Remove the vacuum hose from the fuel pres-
sure regulator.
5. Disconnect the fuel return hose from the
pressure regulator.
6. Label and detach the electrical connectors
from each injector.
7. Remove the bolt(s) holding the fuel rail to the
manifold. Carefully lift the rail up and remove it with
the injectors attached. Take great care not to drop an
injector Place the rail and Injectors in a safe location
on the workbench; protect the tips of the injectors
from dirt and/or Impact.
8. Remove and discard the injector rnsulators
from the intake manifold. The insulators are not
reusable.
9. Remove the injectors from the fuel rail by
pulling gently in a straight outward motion. Make
certain the grommet and O-ring come off with the in-
jector.
To install: 10. Install a new insulator in each injector port in
the manifold.
11. Remove the old grommet and O-ring from
each injector Install a new grommet and O-ring; coat
the O-ring lightly with clean, thin oil.
12. If the fuel pressure regulator was removed,
replace the O-ring with a new one and coat it lightly
with clean, thin oil Insert the regulator straight into
the rail, then check that it can be rotated freely. If It
does not rotate smoothly, remove it and inspect the
O-ring for deformation or jamming. When properly
installed, align the mounting holes and tighten the
retaining bolts to 7 ft. Ibs. (9 Nm). This procedure
must be followed even if the fuel rail was not re-
moved.
13. Install the injector into the fuel rail, constantly
turning the injector left and right during installation.

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.
