i have an 1989 cougar xr7 with a 'supercharged' 3.8 v6 engine

i know that i will soon need to repair the steering column, it needs the supercharger belt, and a master cylinder cap, it has some wiring issues (ex. i have to punch the side of the steering wheel to get the turn signals working, heat, and occasionally brakes to work) i have put a new starter solenoid, and a new (rebuilt) starter. i was driving the other day and when i reached my destination and shut the car off it hasn't started since, i had to tow it home.... the battery has power but i dont even hear it trying to click over??
