The codes don't tell you what to replace, only that the system thinks there is a problem on the circuit, somehwere. How long since over-all tune-up? Use a gage and check fuel pressure. If there is no schrader valve for fuel pressure gage, you will need to tie into the supply line. Make sure, no pressure on fuel system before taking any lines loose.
Erase the codes and see what returns. If you think it is the fuel pump, check fuel pressure first, then check for good voltage and ground at the pump connector. When you first turn the key on, can you hear the pump run for a couple of seconds?
