Engine not running?

Car started fine, drove a couple of blocks and then we parked for a bit. We got back in shortly after, and suddenly it refused to start. Had to get it towed home.

All the electrics appear fine - starter turns really strong - no problems. It just wont kick in.

I am suspecting there is a fuel issue - such as the pump going out or a blockage somewhere. In either cases, I been told its not a quick fix. Unfortunately I cannot afford to get it checked out - so mean time my whole family is stuck in the house. This really sucks.
