8I - 8 IGNITION CONTROL
SPARK PLUG CABLE (Continued)
terminal as close as possible to the spark plug.
Rotate the cover boot 1/2 turn slightly and pull
straight up in a steady motion.Do not use pliers
and do not pull the cable at an angle. Doing so
will damage the insulation, cable terminal or the
spark plug insulator. Wipe spark plug insulator
clean before reinstalling cable.
(6) Remove spark plug cable from coil first.
(7) Always remove the spark plug cable by grasp-
ing the top of the spark plug insulator, turning the
boot 1/2 turn and pulling straight up in a steady
motion.
INSTALLATION
Failure to route the cables properly (Fig. 12) could
cause the radio to reproduce ignition noise, cross
ignition of the spark plugs or short circuit the cables
to ground.
Fig. 12 IGNITION CABLE ROUTING
The system uses two epoxy filled coil packs
mounted on engine block post in the valley under the
intake manifold. The rear coil pack, contains 3 sepa-
rate coils and fires cylinders 1, 2, 3, 4, 6, and 7. The
front coil pack, contains 2 individual coils and fires
cylinders 5, 8, 9, and 10.
NOTE: When replacing the spark plug and coil
cables, route the cables correctly and secure them
in the proper retainers. Failure to route the cables
properly may cause the radio to reproduce ignition
noise. It could also cause cross-ignition of the
plugs, or, may short-circuit the cables to ground.
(1) Install wire separator clip on double ended
stud on rear of engine block first. This is the wire
separator clip closest to the ignition coil insulator
boots.
(2) Connector coil insulator boots over respective
ignition coil side post. Take care to match cylinder
number on ignition coil with cylinder number on
ignition cables. Also, make sure to hear the audible
click while making the connection to the coil post.
(3) Sequentially install wires into separators clips
mounted on double ended studs mounted on the
outer side of valve cover (Fig. 13) and (Fig. 14) and
(Fig. 15). Start from the rear and work forward to
the front of the engine.
(4) After installing all wires into separator clips,
install spark plug insulator boots over respective
spark plugs sequentially from back of engine towards
the front of engine. Make sure to hear the audible
click during installation of spark plug boots.
