I was driving home lastnight when my truck started to skip got a light then stalled, i got it towed cause i could not get it to start, in the moring the truck fired right up. I have scanned for codes heres what i came up with

PO628 -Low vlotage at the lift pump

PO148- High PSI Common rail checksum

PO107- inlet air temp low

PO73- ambient temp sensore to high

PO88- fuel psi to high


I cleared codes and started it back up and the PO628 came back imediatly, so im guessing lift pump issue. I also noticed i have a dual feed line or return line comming from the cp3 to the fuel rail, and its got a small leak from the fitting on the rail just around the threads.....dont know what i should do next. any suggestions or help would be greatly appreciated!!!!
