- 6.4 Powerstroke would blow fuse #74 due to short in high pressure fuel pump solenoid harness. This problem can also cause P0003, P0004, or P0091 if it shorts on the ECM side of solenoid.

I don’t need to do this yet but it’s good info for the noggin! Thanks
Take an hr and lift the cab and front clip up 6+ inches to get at that up pipe and EGR cooler pipe then delete it and the EGR and reroute the back pressure sensor to the block off-end cap. Some creative tube bending will have to happen get the EGR delete kit and DPF Delete with the tuner. That should give your diesel engine an extra 300+k if you're not racing it's well worth the time you needed to replace that harness. Give the turbo a good look over and cleaning. Try to get as much carbon out as possible espesulie on the fresh air side hell through in a bulletproof oil cooler. Hell change your thermostats while your at it. God, you're in there. Put some quality injectors in and change out the injector harness. There is a senceor under the passenger side valve cover change that too. yep, the plastic rocker arm keepers. If your are ambitious change out the main engine harness. That should pretty much clean out your wallet and give you a truck that will last with proper maintenance and keep the tune down at the low side 500k+ miles. Depending on how long that EGR was contaminating the internals and turbo but it's about the best $15K that truck could ever get. You will be happy the truck will love it. You will love that truck.❤ hell I might buy it from you😉😊
