1993 Ford Taurus - Need Help !!!!

Could anyone out there help me with this problem ??
I recently had a new(after market) fuel pump installed in my '93 Taurus
wagon 3.8 litre engine. I did'nt get 12 miles out of the repair shop and
the CHECK ENGINE light came on. By the time I drove back to the shop it
was closed for the 4th of july weekend. A friend had an engine diagnostic
device and read the codes for me. Codes 326,327, and 336,337 came up.
326 = EGR (PFE/DPFE)circuit voltage lower than expected
327 = EGR (EGRP/EVP/PFE/DPFE) circuit below minimum voltage.
336 = Exhaust pressure high EGR (PFE/DPFE)circuit voltage higher than
expected.
337 = EGR (EGRP/PFE/DPFE) circuit above maxamin voltage.
What does this all mean ??? What parts do I need ??? all help deeply
appreciated.

First things first, have you tried to reset the computer and see if the
codes come back? Was the computer reset after the new fuel pump was
installed?
