Getting all these codes...

After changing the EGR controller, the IAC the PFE and MAF I am now getting these codes:

177: HEGO sensor indicates system lean(left Side)
177: HEGO sensor indicates system rich (left Side)
326: PFE circuit voltage lower than expected
543: Fuel pump secondary circuit failure.
556: Fuel pump primaryary circuit failure.

Holy smokes, the car ran better before I started working on it- where do I start?
