I have an 06 ram 5.9 cummins 24v. A week ago I noticed my truck was cranking longer each time I started it throughout the day and 2 times that day on a hill it seemed to not want to accelerate past a certain point then cleared up. Next day same thing in the morning and after work. Following day it cranked for about 10 seconds and didn't start, thought it was the cold so I tried again and another 10 seconds or so before it started. Same again today on a much warmer day. I just replaced the injector pump, pick up pump and filter back in October. I've had a code for intake grid heater since I bought it and I've replaced it but the code has been there for 2 years and I've never had this issue. When I scanned it the other day I had a few codes for fuel delivery and turbocharger over boost. Today it took a few attempts of long cranking before it finally started and there was no codes. Fuel pressure at idle bounces between 6,400 and 7,300 psi. Anyone have any ideas on what to check next? Trucks been down for a week now.
