We have a 2014 LS3 we installed a Kb 3.6L and ID 1000 along with long tubes and a nick Williams 102mm Tb.
Installed a drop in aeromotive fuel pump assembly for this car and we cant get the p023F code to go away. Don't see it in the Dtc area anywhere. We installed the fuel sensor back on car and got that light off this is a full return style system boost referenced mechanical regulator. Any suggestion on the Dtc?
