Ford 2000 3 cylinder diesel not firing

IDK what pump u have.??
If it’s a RoosaMaster or Stanadyne pump, it might have a check ball return fitting..
If it’s a CAV, Lucas or Delphi pump, they do not have a check ball connector..
If u think it’s the connector, simply unscrew it completely and start the engine.. if it stays running, u have your answer.

It's a CAV rotary, being a Ford there's a return on the side plate that goes to the fuel filter housing that I believe has a check ball in it as my brothers 4100 Ford had one that had roughly the same issue (and the pump was just as gross when he got it), he pulled out the ball and spring and it's just ran for the last 2 years... I'll investigate tomorrow, also pull the return line as it could be plugged. I can't imagine why else it would go about idle speed at max governor setting then stall after about a minute...
