Help me fix my car (quote, 2000, Hang, cheap)

I'm no mechanic, but there seems to be something wrong with my car:
It won't start...

Ok, here's the thing. I just bought it a couple months ago, it's an 03' Civic (auto) and has been running fine until today.
I crank her off like normal and she starts up and runs for a good 4 seconds and stalls out.
Tried cranking her off again, but this time it doesn't turn over.
Tried waiting then cranking and hitting the gas, no dice.
Scratched head.
Drank beer.

It's not the battery, just changed it 2 weeks ago.
My first suspicion is that maybe some trash got caught up in the fuel pump or something.
My second thought is that maybe my spark plugs are gunked up?
Apart from that, I really don't know. I have a Chilton's for my car, but I really don't know where the issue lies.

Anyone got any clues?

Edit:
It makes a normal cranking sound, just doesn't fully turn over.
