Had a truck do that a few years back, turned out to be the fuel pump, just saying, something to think about

Ok, might need a touch more info...Is it an Auto or Manual? 4cyl or 6cyl? History on the vehicle? Is it cranking slow, or cranking at normal speed, just not starting?

It does have a check engine light on, I had that checked out a few months ago and they said it was because I had left it running while I put gas in it.

gas cap was off loosing pressure. if thats the only code i would look at fuel pressure. i think its stupposed to be in the 70-80 psi. if the filter is plugged that will keep it from starting. then check to make sure you have spark. and is it getting air?

Do the key trick see if it throws another code
Turn the key to the "on" position three times (or four someone cite this)
And it will show a p**** code.
Also did you try giving it some gas? My tps is bad and I have to give it a little gas on startup

You'd need a fuel pressure gauge. Now there is a test port on the fuel rail (which is where you would screw the fuel pressure gauge into), you could take the cap off of that and push in the schrader valve and see if any fuel shoots out, but then there'll be gas all over the place. That's an "up to you" kinda thing. You'll know if there is fuel pressure or not, but you won't have any idea if it's the proper fuel pressure. If you do get a hold of a gauge, I believe it's supposed to be between 45-50psi...don't quote me on that one, though.
