Hi all!! I am at a loss here!! I have a 2005 Case 410 skidsteer with 1200 hours on it. Recently it got hard to start. I would have to spin and spin and it would fire, then fire faster until it caught. Then it seemed fine! Started when warm no prob. Now I can't get it going. Fires but that's it... I have changed in the past couple months: started, alt, air filter, battery is newer but boosting when trying to fire it now, in line fuel filter, glo plugs, all fuses are fine in the fuse box. I confirmed that there is power to the glo plugs when cycled. My air filter was really really dirty and I have since changed it and I suspected that the inline filter off of the tank was dirty so I changed it, the top screw on filter was supposed to be changed 30 hours ago. Oil seems fine. Block heater works and I added a magnetic pan heater as well. I pulled the fuel hose off that feeds the injectors and there is lots of fuel. I just don't know!! I was leaning toward an injector problem. When i cycle the glo plugs after trying to spin a few times, they just go on and off, don't stay on. Anyone had issues like this????!!! Thanks so much!!
