2013 ram 2500 6.7 died while driving code P008A - Low Fuel Pressure Fuel System Pressure - Too Low
Lift pump tested good with over 10psi and new filters still didn't fix low fuel pressure in rail around 50psi instead off 4500+psi required to start
Took it to dealership and after 8 days they told me it's lift pump in tank low volume of fuel delivered to cp3 and they wanted $1600 so I towed truck back home and replaced lift pump
Same problems low pressure in rail
I removed cp3 pump and found out that shaft broke off in pump
Replaced cp3 pump and problem is fixed no more p008a code
