yea deffinetly a sign you have an nozzle stuck open, air is getting back through the system, meaning you have to purge all the air out before it'll start, that was one of my symptoms too. if you think its your pump, you can check the pressure on the side of the regulator with a guage, looks like a bicycle tire valve on the side of the fuel filter housing, should see somewhere between 30-50psi of pressure. do you know if you have a diaphram pump in the valley of the motor or the electric pump on the frame rail? if you have the pump on the motor it needs to be running or cranking in order to check. 
Please explain to me how a PSD injector can have a "stuck nozzle"...

valve inside the nozzle isnt closing....
if this is the case you should be able to take the injector and plug three of the four holes of the fuel inlet's. put compressed air to one of the holes and watch fuel seep out of the nozzle.
not the most high tech way to do it or the right way but it works.
