There is no FRP sensor on the rail in a mechanical returnless system. Also, if you look at an 08+ code, there is no fuel pump voltage table. Pressure is controlled by a regulator in the fuel tank. I noticed IDS has "fuel tank pressure" which I am assuming to be what the ecu uses...but I have not logged it. I am also not sure if this is in livelink or not.
