Hi Laying Tracks.......I have had a similar problem as well. Through the process of finding out the problem I found and corrected several others. So to make a long story short I haven't started my D2 yet. I have three threads started that go into detail pretty well as to what I found and have had great help from the guys here with solutions. You won't find a better group of people willing to help than the ones here . Check my latest threads here and I think you may find a solution as it is easier to read than to re-post everything. If it still won't crank then I am sure you will get more help here.
I feel my major problem was the fuel transfer pump and from that overhaul I just did replacing of fuel line,main filter replacing and added a pre-filter. Did some work on the governor as well.
Good luck.........Bill
Well there's white smoke and there's clouds of white smoke😊 If you're not getting clouds of white smoke with the throttle wide open, (PULL it open, HARD)........like Bruce says, check the rack. If it's stuck in shutoff, it's most likely because one or more pump plungers are stuck up and not not returning after the cam pushes them up. Spray them with something and work them up and down with a screwdriver. You can also spray the rack bar where is slides through the housing on each end, but it's not normally the problem.
Many of these old tractors will not show good fuel pressure until the main engine starts up, so if it registers any pressure, I expect you're good to start. You could go ahead and check the pressure control valve down on the fuel inlet block, since it is what controls the pressure of the fuel that makes it through the filters. Of course the transfer pump has to create any pressure and may be worn enough that is just won't do any more than that.
Another thing to check is whether you have sediment covering the pickup line in the tank. You may want to pull the fuel line on the tank side of the filter and blow back into the tank.
Be cautious with the starting fluid. If the engine hadn't needed it before now then using much of it is not a good idea until you're sure about whether there is fuel going thru the injector lines.
As 83 Jim said make sure your getting fuel to the pumps. Pull the throttle on and turn the engine over and loosen each fuel line one at a time and you should be getting fuel coming out the pumps if it,s getting fuel.Also as was mentioned before, pull the side cover off the injection housing and see if the rack moves when you pull the throttle off and on.
