Did you check the fuel-pump by cranking the engine over or are you testing with the hand-primer? The latter can make a false test.
If you are dead-sure it is getting fuel to the injection pump - you need to verify the pump is actually turning. Just take off the timing window and look inside when the engine is cranking. 1/2 of what you see should be rotating. If not, the driveshaft is broken and it is likely the pump is shot.
If you ascertain the pump IS turning inside - I'd take the three-bolt cover off and see if the metering valve is free.
If that is okay - I'd then hook compressed air to one of the high-pressure discharge ports and rotate the pump until whatever port you use is in inject position. The air will travel backwards and go against the two fuel plungers. Sometimes this will free them up.
