I went from pin b6 black which is supposed to be the ground for the ect sensor and I'm not getting any resistance and no continuity which from what I understand I should be, so would that mean I have a break somewhere in the ground wire from the Ect to the pcm?

That's weird how it reads ambient temp within 30 seconds. When my coolant sensor was bad, it threw a code and I used a scan tool to diagnose it. I just followed the diagnostic in the FSM. Just make sure you're reading temp in fahrenheit, and not Celsius. I say that because I was reading it that way, and it threw me off.

Yeah that's what was throwing me off but I fixed it, it was a cut, literally cut ground wire. I know the PO had all the work done by a "specialist corvette shop" and that they wanted to buy it. I almost have a feeling they cut the wire for some reason.
Once I soldered the ground wire back together everything works great.
It was just how it would heat up correctly until you shut it off then everything was messed up that really confused me.
Now I just need to figure out why it won't connect to my scanner

Look into using something called blue devil. It's a Bluetooth obd2 connector that connects to the aldl port, and you buy an app for your phone. I have not used it, but have heard good stuff about it. I use something similar on my 93. Not to pull codes, cause I can do that with a paper clip, but to datalog. I believe you can also pull codes with a paper clip on a 96?
