I am having what I think is a fuel delivery problem on my 3010. We were using it to drill some post holes, when it started losing RPM until it stopped. Worked with it a little and thought it was the fuel pump. Replaced the fuel pump and still get the same thing. We can get it started, but it will not respond to the throttle, then just loses RPM until it dies, then won't start. There is fuel pressure to the injectors and pressure in the injector pump. We checked the fuel return line that runs from the injector pump to the injector, then on to the fuel tank and it seems to be open.
We found that if we loosen a particular cap screw on the injector pump, the release of pressure seems to allow the fuel to flow, then the tractor will run, but not well, while fuel is spurting out from the loose capscrew. The screw is one of the two that are safety-wired on the parts diagram. I have indicated it in the attached photo.
Any ideas?
