first off you may just have a bad solenoid and not the starter. i know most older fords the solenoid is not part of the starter assembly. its located elsewhere. i do not know on the taurus. also check your main wire going from the solenoid to the starter (again only if it is not one unit) sometimes with high milage cars that is the issue.
step 1 bench test the starter and solenoid by clamping it in a vice and putting a 12v power to the proper leg of the solenoid. then there are two terminals on the solenoid a ground and a 12V it works both ways so dont worry. apply 12v and ground and see what happens. you will also have to chassis ground the starter to the negative of the battery as well.
if the starter doesnt kick off then bypass the solenoid by jumping the two terminals with a screw driver. Makes alot of sparks but wont hurt it. if the starter kicks to life its the solenoid.
as you stated the solenoid is clicking so its not ignition based the solenoid may have just broken inside.
i have also gotten bad starters from the autoparts store if they are remanufactured.
Starter and solenoid are one piece. Already bench tested before
I installed. It works fine. THANKS for trying though... Appreciate it
