Ok, so now we know its not an ignition problem, you've got spark. Not compression issue either. So again its fuel. Its not getting there for a couple of reasons. The suspected fuel relay or a plugged fuel line. Disconnect the fuel line before the fuel filter (between the gas tank and the injector body). Start it and see if any fuel pumps into a jar.
Thats why I was hoping to take the fuel pump out of the equation.
