Hi guys, got a h8.0FT6 with Kubota v3800t engine. It will eventually start with some easy start in the air intake, but will not idle. Briggs diagnosed blocked injectors, took them out and tested fine. All pressures as expected when it runs, but it will not start without easy start and accelerator needs to be to the floor to keep it going. I've recently stripped out the EGR valve as it's showing as stuck open at 12%. Valve was very coked up but cleaned up nicely, replaced it but still the same problem, could be the motorised controller which has failed, but would this stop the engine from starting?
