cranks but won't start?

Fuel pressure is good while it's cranking. 48-49 psi. Kind of stumped and tired of going over the same things. I have added extra grounds and double checked all the grounds and fittings. Does the alternator not charging have anything to do with it? I charged the battery last night so it's good. I just ordered the elm scan tool and i will get the torque app. Just don't want to wait 2 weeks for it.
