Massive Screw Up, Need a FSM or some basic help

fixd, a while ago lol. Stupid wiring error lead to this happening.

In addition, someone had to move the car out of my shop to use the space, and put a key in it with no battery. I cant remove that key right now, its stuck in the ignition. Not sure if that has anything to do with anything, but i read somewhere about an ignition lockout or something.

Time to get a meter or test light and go through the main cables one by one, starting at the battery.
As for the key, there is a way to release it, I think you can stick a small shaft in a hole in the column. I have read on the blazer forums of people using a drill bit, but I am unsure what size. Check here, starting at post 5.
