Does it crank over real strong? Or does it sound a little weak?
I was at AMP a few weeks back and a guy brought a 2010 truck in because it would randomly run bad after starting it. It had a weak battery and it was strong enough to crank the engine over but it was so borderline that the computer was losing crank signal during the crank. I hadn't seen that before but apparently Sam had, he went right to the issue and saw the crank signal dropping out during cranking. The guy had a little fork lift battery or something like that in there.

If you hear the fuel pump and also tried spraying starting fluid in it and it still doesn't run it must be ignition.
I'd go for battery first, then cam or crank sensor if that doesn't help.
If you have a jump box around connect it up and turn it on and fire the truck with the battery and jump box, if it fires right up you know you have a weak battery. You could also boost it from another vehicle for a few minutes before cranking it, in other words jump start it. That would help tell you too.
