What does it mean they are "barely communicating?" I know their shop computer is probably pretty fancy, but your '93 uses an old-fashioned EEC-IV computer. Did anyone try pulling codes the poor man's way with just a jumper wire and a voltmeter/test light/check engine light (see tech article in Ken00's tech info post in Bronco II forum)? I'm sure there are some possible issues with communicating with an EEC-IV computer, but pulling trouble codes shouldn't be one of them.
When you checked fuel pressure, did you check for gasoline in the vacuum line to the fuel pressure regulator? That's one somewhat common failure mode for the FPR.
