If you are not getting any fuel out of the injection pump then shimming will not help (unless there was a ridiculous amount of shims installed). Also if you are not getting any fuel out of the pump then it should not smoke either. Are you not getting any fuel out of any of the cylinders on the pump? Is the throttle in the full throttle position? Is the governor hooked up for sure? What happened to the original pump?
