Where on the 1994 4.3L Chevy Caprice Classic w/ MFI system is the Schrader valve located? Also, where is the MFI test port located?

If I understand your question, the schrader valve to hook up a pressure gauge is located at the right (passenger side) rear of the top of the intake manifold. It's right under or near the wiring harness. You will see two lines coming in from the left, those are the fuel and return lines. They go into the fuel pressure regulator and just past that is the schrader valve. It has a cap on it.

Here is a picture. The pink thing is pointing to the schrader valve. You do have to remove home plate and you can see, it at the right rear corner of the top of the intake. HTH.
