What is the 7045? What engine do you have? Have you checked the fuel supply from the tank to the first filer? This is where any debris would restrict the fuel supply to the system.

Allis Chalmers 7045 , stanadyne pump. We checked fuel and changed filter there is nothing restricting the fuel. It will start right up, rev up but slow. If you let up on it it will die and then start right back up.

Have you removed the return fitting in the injection pump to see if the return may be restricted. The return fitting is typically a check valve and if stuck, pump pressure builds and can keep engine from running. Check the fitting and the line back to the tank, to be sure it is open. If no problem with the return, I would make a test line from the electric fuel pump inlet, back into the fuel tank opening, bypassing all the parts before the electric pump. If no change, I think it would be time to have the pump checked!

Already did this. I am a diesel mechanic and have done all of this. Something must be wrong with governor I 'll have to take it off and send to a shop to be rebuilt.
