FIXED IT.

Before I called it quits for the day, I checked every single fuse in the fuse block. Found the ECM fuse was blown. (Must have been from disconnecting the PCM without disconnecting the battery).

Never thought to check that fuse, as everything worked like it should, besides the fuel system.

Anyways, replaced the fuse and car runs. ZZP PCM is in now, and we are back to where I left off. Time to do some scanning with the other PCM installed and see what readings I get.
