My 4020 engine replacement is done, but I can't get the injection pump to work. I have bled everything, and have fuel to the pump. The engine is from an early 7700 combine, CBC633-26AL. The fuel shut-off has a faint click when I turn on the key. Is there a way to make sure it's opening? Any suggestions before I take it to the rebuilder?
First pic is the CBC pump, second is the DBGVC on the blown engine. Would like to change it over, but the mount is different.
