Okay so it is a fuel issue. Did you crack the lines at the injectors? That will tell you if your getting fuel to the injectors. If nothing there, pull the line off the filter that runs to the injector pump and crank it to see if fuel is coming out. The line runs under the manifold to the injector pump and is a bit of a pain to get to underneath, but you can pull the line off at the filter and put you a small piece of hose on the nipple to see if fuel comes out when your cranking. I know it's frustrating, but check it step by step as the fuel is suppose to go to see where the fuel is making it to.
