First thing to do. Disconnect all ground wires, scrape or sand down to bare metal and reconnect. Replace positive and negative battery cables.

All Corvettes are notorious for grounding issues.. If the battery voltage is 12.5 or so the promlem is probably a ground..

Ok I SHOULD have 12 volts at the purple wire... I have full power at the battery and starter, and i have a charger hooked up just in case. Maybe the purple wire has become brittle and has gained some resistance? Im gonna try turning over the starter with a screwdriver tomorrow to make sure im dealing with a good starter... maybe the solenoid fried that purple wire...

If you picked up restitance it's more likely in the switch that's at the base of the column where the purple wire connects to the primary power supply. If that's the issue the good news here is that you don't have to take the column apart to replace it.

Hello fellow hot rod vetter! If your wiring is close to mine, the purple start wire should come from you key switch, easy enough to check voltage at the base of the column at the flat connector, check for 12vlts going in and out. And, get a Mid America manual, they have the wiring diagrams, makes it real easy to back track any electrical issues..
