If you had removed the Injector Pump previously, and the above does not fix the problem, it may be the Injector Pump Timing Shim(s) are missing or the Yoke (from the governor linkage inside the engine) is not engaging with the Injector Pump.

You can check the Yoke by removing the inspection plate on the front of the Pump and moving the Run/Stop lever. It should move the Yoke left and right, and in between the Yoke you should see the "Pump Pin" move too. If not, you will need to reinstall the Pump so this Pin is sitting between the Yoke. Please let us know if you need help with this.
