2005 Case IH JX1090U, supposed to be same engine in the same vintage Case 580 backhoes. 90 engine HP.
5-6 years ago I went through a time of fuel siphoning back to the tank when tractor wasn't running and sitting, first 1-2 weeks, then a couple days, then a few hours. Had to fix that. What I did was mix up a a concoction of different additives including Diesel Medic, Transmission fluid, 2 cycle gasoline mix (no gas) and Sea Foam and guys said "Run her hard!"
I did, and it quit, and every time I would fill up I added a quart of trans fluid or something but I got away from that maybe the last year and last week when I was cutting hay, I idled it down and kicked off the PTO and in the process of all that the engine quit. Would not restart without giving it throttle with foot pedai or throttle handle.
I changed fuel filter and blew the air filter out since I didn't have a replacement on hand then mixed up a new batch of additives in the fuel, and used a thermo heat gun and determined when it first started 3 injectors were within (1-2) degrees of each other and one (#3) was 15 degrees hotter before the engine warmed up and everything was same temp.
I had hay on the ground and ran her hard baling hay today. It would alternate between bogging down, taking it's sweet time to idle back down and and stalling around original idle range.
I think I have maybe two issues? A sticky injector and now something wrong with injection pump. 3700 hours, original owner.
Sorry for the long write up.
