EFILive does not the necessary efan parameters mapped for Gen IV+ ECMs to change to other options, you'll need to source a file with those changes made or have someone provide you a .cax file with the tables mapped out.
For fuel pump, if you don't have a FSCM fitted, I'd look at F0585 and the other tables in the Fuel System -> Fuel Pump area. As to what exactly needs to be changed from PWM -> on/off, not able to answer that at time time - my Gen V experience is limited.
