Hold throttle in idle position and install new pump cover seal. Making sure that screws are not in cover, position cover above 1/4 inch forward
toward shaft end and about 1/8 inch above pump, Fig. 56. Move cover rearward and downward into position, using care to avoid cutting seal, then
reinstall cover screws. Each screw must have a flat washer and internal lock washer, with flat washer against pump cover. Torque screws to 33

On all models, reconnect both battery ground cables, then turn ignition switch to run position and touch pink solenoid wire to solenoid. A clicking
noise should be heard as the wire is connected and disconnected. If not, the linkage may be jammed in the wide open position and the engine must
not be started. Proceed to step 26. If clicking is heard, connect pump solenoid and housing pressure cold advance wires and proceed to step 26.

Remove cover, then ground solenoid lead (opposite hot lead) and connect pink wire. With ignition switch in run position, the solenoid in the cover
should move the linkage. If not, the solenoid must be replaced. Minimum voltage across solenoid terminals must be 12 volts. Reinstall cover and
repeat step 25.
