1990 Ford Taurus

Hello,

Does the vehicles engine spin when you try to start the car or does it just click or does nothing?

If does nothing and you have replaced the Battery and Solenoid, Alternator would really have much to do with it not starting if you put a new battery in it, so the next thing to check would be the Starter. If you can do the work then remove the starter and take it to your local parts store and see if they can test it.

Well yes it does.
