I have an 08 ram 3500 with the 6.7. Truck started stalling when hot. Hooked up scanner to find high pressure fuel dropping off. Found relief valve was leaking off. Installed rail plug and still drops off hot. Checked lift pump pressure, got 10psi dropping no lower than 7 after long pulls. Swapped fuel filter and FCA. Still stalls. Replaced cp3. Still stalls. Finally got mad and performed return test. Came back at 300ml in 30 seconds. Replaced all 6 injectors. Truck is Still stalling. Cold will maybe build to 18-20000 psi, and continually drops until it stalls. Anyone have any ideas before I burn this thing?

I would replace your lift pump with an aftermarket one, like AirDog or Fass. To me that seems pretty low for fuel pressure.

Look at these instructions when it comes to swapping the injectors. But the fuel pressure isnt bad but I would look into getting a fass or AD 150 for the truck to help insure wsmooth operation of the injection systems. How did the connecting tubes look when you swapped the injectors on the truck?
