I have a BX2200 (D905-E engine) and I have rebuilt most of the engine and would really like to see it start (smile). I think I may have a problem with the injectors, but would like some input. When I remove the lines from the fuel injection pump to the injectors, fill the injectors with fuel, and turn the engine over it throws the fuel a few feet into the air thus emptying the injectors. Is that what it should do or should the injectors effectively be a check-valve and not allow air from the cylinder to come back through the injector? Basically I'm trying to figure out if I need to replace the injectors. I just put a new fuel infection pump on the engine... Thoughts?
