7. FUEL INJECTOR REPLACEMENT, (1999-2000 “returnless fuel” vehicles only)
A. Disconnect the EGR tube from the EGR valve at
the rear of the upper intake manifold. Remove all
bolts securing the upper manifold to the lower
manifold. Unplug the electrical connector from
the fuel pressure sensor. The upper manifold
should move up enough to access all fuel injec-
tors.
B. Disconnect the six fuel injector wiring clips and
retainers from the fuel injectors. Release any
residual fuel pressure from the rail by opening
the schrader valve.
C. Remove the plastic from around the injector
wires. Remove the bolts holding down the factory
fuel rail. Lift up on the rail evenly and remove all
six injectors.
D. Using a small amount of clean motor oil, lightly
lubricate the O-rings on both ends of the Vortech
supplied fuel injectors.
E. Install the new injectors into the fuel rail with the
terminals facing outward.
F. Carefully lower the fuel rail/injector assembly
down onto the intake manifold. Check to see that
each injector has been seated properly.
G. Tighten down the fuel rail assembly with the
original bolts.
H. Use the supplied jumper harnesses to connect
the factory fuel injector plug to the newly installed
fuel injectors. (See
Fig. 7-a.)
I. Zip tie the jumper harnesses to the fuel rail so the
stay clear of the manifold when reinstalled. (See
Fig. 7-a.)
J. Reinstall all previously removed components.
