21. Disconnect the special service tool.
22. Install the vapor shut-off valve to the
throttle body assembly.
23. Install the throttle body assembly. See
“Installing the throttle body assembly” (6-
24).
24. Install the intake manifolds. See “Install-
ing the intake manifold” (6-18).
25. Install the intake silencer. See “Installing

Checking the lighting coil
1. Remove the intake manifold (STBD).
See “Removing the intake manifold” (6-
17).
2. Remove the stator assembly leads from
the plastic ties

, and then disconnect
the stator assembly couplers

.
3. Move the stator assembly leads away
from the area covered by the intake man-
ifold, and then install the intake manifold
(STBD). See “Installing the intake mani-
fold” (6-18).
4. Measure the lighting coil output peak
voltage between all combinations of the
terminals.
TIP:
When measuring the output peak voltage
under the cranking condition, remove the clip
from the engine shut-off switch to prevent the
engine from starting.
5. Measure the lighting coil resistance.
6. Remove the intake manifold (STBD).
See “Removing the intake manifold” (6-
17).
7. Connect the stator assembly couplers,
and then fasten the stator assembly
leads using the plastic ties.
