No fuel to injectors on 1966 Ford 4000

I have a 1966 Ford 4000 four cylinder diesel tractor. It has been as solid as a rock for the 5 or 6 years I've owned it. It starts right up in
cold weather or hot weather. I tried to start it yesterday and the engine turned over very well but it didn't even try to start. Today, I checked
the flow of fuel to the fuel filter, and the flow from the filter to the injector pump and all was good. However, I have no flow whatever out of
any of the injectors. It's a Stanadyne injector pump. The throttle linkage to the pump is free and operates through its entire range of movement.

So, this question might be so simple it's foolish, but here goes. I know virtually nothing about diesel engines. What do think? In my simple mind
it seems like the injector pump has failed, but it is an overnight failure, the tractor was working fine when I parked it in the shed a couple of
days ago.

Any advice?

From what little I know it may be the metering valve in the pump.
I believe that means a pump overhaul.
 
How full is the tank if empty it can sometimes look like plenty of fuel and not flow enough to start. Then is there a lift pump like your old chevy has on it if so it might be bad pull it off and work the lever to the cam shaft if it squirts fuel a long ways in a good stream it is probably ok. Then If you have not removed the return line off the pump it might have a plugged return not letting it start. Or if the rack is stuck in the off position it can't start till it is loosened up. Not sure what pump it has so some of this may not apply .
