bought a d2 with a broke pony. Pop started the diesel to get it on the trailer. I let it run all the way home (2hrs) then got it off the trailer. Diesel worked fine. Got the pony running but now the big engine won't start Fuel up to the injectors but no smoke when its cranking. Starts poping when I spray wd40 down intake any Ideas would help would be appreciated, fuel gauge is in normal range tank has 12 gallons.

No smoke is either no fuel or no compression, given that it was just running so can rule out other issues. Given that it pops on WD-40, it's probably no fuel. Just to be sure, the decompression lever is set to Run when you attempt to start it right? When you bleed the injectors, make sure the governor lever is OFF, not part or full throttle. It can look like you have fuel at the injectors and the transfer pump can be putting out pressure but unless it's squirting, then there's still air in it. Prefer to bleed using the bleeders behind the fuel pumps, rather than cracking the lines to the injectors - they only have so many retightens in them. Try putting 2-5psi air pressure in the diesel fuel tank and/or fill it up to the top. Just some ideas for you.

decompression lever set to run, put air hose to tank, bled all lines using the petcock behind fuel lines nothing. Its squirting out no air bubbles but also no hint of fuel in the cylnders don't know much about injector system but I think it is unusual that it ran fine till I shut it off and let it sit for about 1 1/2 month

No mention of sitting after parked. Sounds like a stuck fuel rack, but that doesn’t explain a main that is locked up. JM

It's possible that your injector lines are blocked, and/or your injector nozzles are stuck open. In this case, slacken the injector lines at the injectors, and bleed there (I know I wrote before that this is not preferred but since you have good output at the pump bleeders, we need to verify that you have fuel all the way to the injectors). If you have good output at the injector union nuts, then try to start again. If still no smoke, try winding the main engine over by hand, to confirm that, regardless of where the decompression lever is set, you can feel good compression by hand. Sometimes the lever can be set in the right position but not be correctly setting the valve depressors. This likely isn't your issue since you haven't reported messing with that part of the machine, but it's still good to check it off the trouble-shooting list. Usually you can tell if the compression is correctly working because when cranking under compression on the pony, the engine sort of "jumps" a little and you can hear the difference between no compression and compression.The pony should noticeably sound like it's working when changing from no- to compression

if it could be a stuck rack how would I access it?

Hi Team,
not unknown to have the injection pump plungers stick in the shut off position with water laden fuel.
The rack only moves to the fuel on position by the tension of the governor spring tension so is not a positive forced movement if anything like the plungers or the rack are sticky.
If the plungers are found to be stuck up--not going up or down-- then DO NOT Turn them but gently tap and/or lever them up and down to free them--turning them can shift the plunger gear on the plunger and loose the factory set position as it is only clamped in position.
If the plunger gear turns then that cylinder will get more or less fuel injected than the others and so engine will run rough.

Other issue sometimes after sitting it can take a good hard snap back of the operators governor control lever to get the inner fuel injection pump governor mechanisms past the shut off detent and so shift the rack to the run position.
Cheers,
Eddie B.

Yank HARD on the throttle. Very good chance the rack is stuck in the off position.

I will try tomorrow but two questions I have are, where should I tap around (around the throttle handle)? Also which way is throttle on/off and if I were to tap the throttle handle which way should I tap it. Side note the handle doesn't seem to have anything attached to it. We will see in the morning Thanks to all Michael

Maybe the linkage fell apart some how? Use the handle right the injection pump.
