ive cracked the injector lines at the injectors to check for fuel and there was definitely fuel coming out
anyone have any thoughts? am i missing something obvious?
Thanks in advance, Jack

Did you aquire and install an Oil Pan on the Engine and put Oil in it?
Running an Engine that has sat al long time and all the Oil has drained out of it and gotten thick dand maybe even hard over time is only going to ruin bearings and journals when cranked dry.
If you have read other post you will here of people speaking of a hand held vacuum tester generically known as a Mighty Vac (there is also a real product called a mighty vac).
It is a hand vacuum pump with a gauge on it.
If you connect that to the Governor Vac connection you sould be able to pump and get some vacuum to displace the Diaphragm in the Governor.
However, that is not the whole story. If the Engine has sat a long time there is likely rust or at least dried fuel inside of the Elements (plungers and barrels) of the fuel Injection Pump.
What can happen is that the element plunger goes up and the crud sticks it up there as it only has the force of the spring to return it back down.
There is a rectangular cover behind the fuel supply/lift pump and you can remove that and see if the springs are pushing the Plungers back down.
So it is entirly possible that all of the element plunbers are stuck up at the top of their stroke.
On an engine that has sat for a long time it is benificial to remove the fuel injection hard lines when you are first cranking so that you can immediately see if fuel is going to come out of the top of the Fuel Injection Pumps.
Never block the holes that the high pressure fuel is going to come out of with your body parts as it will/can inject into you skin and leaves a really nasty and hard to heal wound.
Also resist the temptation to get you face over the top of the fuel injection pump while the engine is cranking as it can easily spurt up into your face and eyes if it is working.
