It sounds like the pcm has failed. You said you verified power to the pcm? There may be more than one fuse that controls the circuits. If there is no voltage to the egr, that is a 12 volt feed fed from an outside source.
Check the fusible links at the starter or by the fuse block. It sounds like you have a power supply issue.
Does the check engine light come on?

Was this
