I assume the starter will crank and you meant to say that the engine will not start or run. It seems to me as though the fuel injectors are not working since the fuel pressure is ok. Check for voltage to the fuel injectors with the key on run and if no voltage check the fuse to begin with. If there is voltage to the fuel injectors then I assume there is no pulse while cranking over the engine, so then check the fuse for the ecm/pcm and if it's ok, you could be looking at maybe a faulty crankshaft position sensor if this is equipped with that, so do you have any scan tool or code reader that can read codes?

I see 2 fuses for the fuel injectors, a fuse #18 and #22 in the underhood electrical center. INJR 1 and INJR2. Here is that wiring diagram,
