This is a long shot, but is the return line to the tank plugged? I can tell you first hand, those Fiats are the hardest tractor to start after running them out of fuel that were ever built, but as a general rule, once they fire, the air is generally all out and the process is over.

Thanks Rrlund.

The return line is plugged.

I tried bleed it again. The point I reached: at full speed, the engine starts, but will not make more than 500 rpm. And if less speed, no fuel to the injectors and the engine dies.

So, my hypothesis is that I somehow misplaced the stopper or the plate, in the injection pump cover. I am going to reopen it now, and see if this may be the issue.

I'll keep you posted.

So, I did open the injection pump cover, made sure everything is in order, and i'm quite sure it is the case (I did watch the Bundy Bear video on the matter). Bled it again, and same result...

Engine starts at full speed, but won't go over 500 rpm, and if I give less gas, there is not enough fuel going to the injectors and it dies... It's a pain.

Thank you all for your help and insights.

I just got to thinking about something. In the other post, you said it had been sitting for a year. Is the intake plugged by any chance?
Maybe a mouse or mud dobber nest? I left a diesel tractor sitting outside the shop one night with the hood off and I put a plastic
coffee can over the intake. I forgot to take it off when I stated it the next morning and it acted pretty much like you describe.

Thanks rrlund, and thanks derwen,

Intake: I will remove the air filter to double-check. I had to remove it to remove the battery (another story...), but I put a bag to cover the intake (and I did remove it when reinstalling). But maybe a mouse got in anyway. Thing is, I was told that the exhaust smoke would have been black if air was missing. Which is not the case. Plus, I can see there is an issue with the fuel coming to the injector: when the lines are open, it is only at full speed that the fuel is spurting. That is why I don't think intake is the issue. But your comment convinced me to take a look anyway.

Lift pump: with my father, it has been one of the theory, so we removed it, and realized it seemed to be working properly. And if I pump it enough, fuel is going back in the tank through the return line. Is it possible that it is, nonetheless, not working properly?

Just wondering if you changed the fuel filter and if it uses a Wix 33166 filter element like is used by most Fords and Massey Fergusons?
