Unfortunately, no!! I do have an OBD1 scanner from Autozone and no codes come up, and I'm not able to see live data. I plugged and pulled tss and vss with no luck.

I do know the obd1 port works because I pulled the TPS and it threw a code. I'm at a lose for what the heck is going on. Everything on this the engine and tranny are brand new.
