trouble codes

my f150 5.0 has been runnign kinda lame latley
so i decided to get the codes
key on engine off
539-- got this 2 times in a row but no meaning for it in the book
539
327--EVP or DPFE circuit below minimum voltage
332--insuficient EGR flow detected
334--EGR closed voltage higher then expected
556-- fuel pump primary circuit failure
539 does not exist in my book
when i did the test key on engine running i got
411--cannot control rpmduring KOER low rpm check
538--insufficient rpm change during koer dynamic response test
and it would not stay at a constant idle



my question is do these codes seem right and what is the 539 code for
also im trying to make light of these codes
i am guessing my egr valve is hooped
evp or dpfe circuit and fuel pump primary circuit i am baffled about
can anyone make light of this

I got that code 539 is "system shows voltage at PCM pin 10. Is A/C on"
I do not know if this means something to you

I also run EEC -IV codes and I am getting 542 which is "fuel pump open, bad ground or always on.

My problem is how do I fix it.... any ideas?????
