Need some help here
2015 ram 6.7 Cummins. 331k miles tuned & deleted
Stock fuel system
For the past month I’ve had random stalls but always refires.
Until yesterday. Per my mm3 I noticed the desired rail pressure was a good bit higher than actual. Then the actual started to drop the the point that the truck lost power and eventually stalled out.
I put a new relief valve on it. Put a new fca on it. It’ll start back up and run ok for a minute but then the rail pressure drops again. Unplugging the fca yields 26k fuel pressure but trying to drive it like that it slowly drops and stalls out even with fca unplugged.
All this started when I put a transfer tank in the bed. I’m thinking maybe I have a bad injector?
I don’t think it’s the cp3 because it will still build 26000 sitting still fca unplugged.
And the idle is kinda lopy
No white smoke. Not smoking at idle. Only black smoke when it fuels up like Any deleted diesel. No skips oil not rising
Any help is appreciated I’m ready to trade this thing off for a gas job
