Shop & Owner STUMPED: Cummins Can't CHARGE? Fuel Pressure PROBLEM? (P0254-P0088-P0691-P0541-P1475)
This clean 2014 Ram 2500 Cummins Turbo Diesel only has 60k miles on the clock.
Just recently, the owner said that some warning lights came ON and it stopped CHARGING the battery!
Strangely, there are no "Alternator" DTCS...but there are codes for the Fuel Pressure and Cooling Fan Circuits. "P0254 Injection Pump Fuel Valve High Current" is concerning.
Another shop had it for 3 weeks, and GAVE UP after throwing a Fuel Regulator Valve at it.
Let's see if all of these random codes are related, and if any parts will be required for the repair...
