I have a 2016 4010, I’ve been digging into a low power issue. The fuel pump was replaced a couple years ago and for some reason I started there with my troubleshooting and replaced the filter with no change. Next I cleaned the throttle body with no change, it was then I realized that the rear cylinder wasn’t firing, I replaced the ignition coil convinced that was the issue but no change. I did find a broken wire below the front coil (blue-pink) attached to some plug bolted to the engine, at that point I was frustrated but relieved that this could possibly have been my issue all along but after fixing the break with a butt connector , but no change, does anyone have any suggestions or ideas? The broken wire is the same color as a wire going to 3 different sensors on the throttle body

 

I have a 2018, same problem...no dfi light... Let it sit for a few days (after its flooded from following symptoms) and fire it up, it runs for about 2 minutes o.k. then drops rear cylinder. When I pull the plugs that's the one that is wet, also with plugs out I can see the spark on both plugs... replaced fuel filter, pressure regulator, ecu, plugs, injectors, checked fuel flow volume and pressure at 41 psi..... nothing has fixed it. I verified that the intake is open and clear, the exhaust is open and clear, Air filter is new............... I cannot find a code reader for the 2018 so no help with obdII. Has anyone solved this problem? This unit has only 30 hours on it. Guess Im going for rear coil next??!!! Or trailer this POS to the stealership for out of warranty repair!!!
