have a 1993 astrostar, relaced the upper control arm, now wont turn over no electric, run before why?

Answer 1

Retrace your steps when your worked on the upper control arm. You probably hit a wire or blew the fusible link located in the wiring to your starter.
good luck.......

Answer 2

Remove, clean and tighten your battery connections and replace your battery if it's 5 years old. Otherwise have your battery load tested at the auto parts store to make sure it's good.
