i'd start by checking to see if fuel is reaching the injectors. if not, trace it back to the injection pump and check to see if fuel is arriving from the tank.

does the tractor have an electric fuel shutoff solenoid?

i'm not an expert, but those are some starting points.

i got the thing to run by priming it lots and either it took 4 hrs and then it ran fine and started okay now that has sat for two days i have to do it all over and its so frustrating and i have tryed 3 different dealers that say yeh we have had a few that wont start but we dont know what it is bring it in and we will change parts at your expense until we find the problem. I can do most all of that at home is what i told them
