If fuel is getting to the injectors but not the cylinder it's a good bet that's where your problem lies. Check the wiring.

do you hear the pump prime when you 1st turn the key...before trying to crank? the thing to do with this problem is too figure out what the evo uses to fire the injector (cam position,crank position) and make sure that is functioning properly

have you put an actual fuel pressure gauge on the rail?
You might have a bad pressure regulator, so its not making resistance in the rail to have pressure, but it has flow.

Also, take the plug off the injector and use a test light to make sure you have power/ground while cranking the engine.
