That fuel rail pressure code had me chasing ghosts for 3 days
Truck came in with a P0087 under load, a 2017 Freightliner Cascadia with a DD15 in Phoenix. I replaced the lift pump, checked the filters, and even swapped the fuel pressure sensor before I found the real issue, a worn camshaft lobe on the injection pump drive. How long do you guys usually spend on a mystery fuel supply code before you start pulling the valve cover?

Man, a buddy of mine spent a whole week on a P0087 before he found a chewed wire harness on the frame rail. Makes you wonder how many parts we throw at these things before we actually slow down and trace the fuel path, right?
