We just replaced the fuel filter and had the injectors rebuilt on our backhoe, and have gone by the book to bleed the system. First the fuel filter, then injector pump, then the injector lines at the injectors. Bleeding the filter and the injector pump worked great, but we can't get any fuel out of the injector lines (the high pressure side of the pump). We've verified that we get good fuel flow to the pump. The fuel shutoff appears to be in the correct position (based on how it has always worked).
Any ideas, short of having a tech. look at the injector pump? It seems like it should be pretty simple, so I keep thinking I'm missing something.
By the way, everything worked fine a couple of weeks ago, when we noticed it was loosing power under load, so we found one of the injectors was weeping. We had them all rebuild.
