I am trying to diagnose an issue with my 2003 F-250 6.0L PSD.
The first time I crank it everyday, it struggles to start.
Beyond that, it seems to run fine and not have issues cranking throughout the day.
I've recently replaced both batteries, the FICM, the fuel filters and the FI wiring harness.
Any thoughts on what could be the issue?
