I picked up my grand paws old tractor that is in sad shape, he is getting up there in age and hasn't used it in years. One brake was lock up and didn't run at all. Got it home and moved it inside to start the investigation process of figuring out what made it get parked to start with. First issue ball nut steering gone out, FIXED thanks to this forum. Now to changing fluids first fuel I removed the tank and the mystery stuff I found in there. Like a grab bag of odd things from the fuel cap gasket to a pine limb and everything between. OH boy I see problems replaced fuel filter and blew fuel line out between tank and filter. Then to the injector lines and bleed the system. Got a solid stream of fuel out of injector one a slight dribble out of number two and not a drop from number three. Any suggestions? Does having them all out at once change the pump pressure where if one is free flowing fuel and that doesn't allow the other two enough pressure to get fuel through them? And how do you test your glow plugs as well? Trying to get it running so everything else can be assessed like smoke blow by and hydrolics Transmission and all. Has a FEL on it as well. Any ideas. And if the pump has to be rebuilt can it be a do it yourself project or best left to the pros even on a tight budget? Thanks for any responses
