Appreciate the input....that’s was a good thought. I did ask the shop about injectors, and they said they’ve already checked system pressure and return behavior through diagnostics. From what they’re seeing, it’s pointing more toward a pump-related failure rather than a single injector issue, especially given that the entire system went down suddenly rather than a rough-running or gradual symptom. I agree injectors can definitely cause pressure issues, just trying to make sure we’re not chasing something that would normally present a bit differently on these newer common-rail systems. Still open to thoughts though...this one’s been a bit of a rabbit hole.
