Bob just follow the White and Red wire from the new relay you installed--you will find a connection near the body stabilizer--check that it is clean and tight!

The main starter power comes from the pas side firewall area just to the area behind the cam cover.. it is a 9/16th nut ( or a 15 mm ) under a rubber shield, it may be loose... ( in the engine bay )

There is a difference in the car not cranking and not starting--I assume it will not crank--if not check the plugin to the starter for corrosion--it is on the Rh side of the endine near the stabilizer brace.
