Check for spark - take a plug out of the block and hold it near to the block to see if it sparks (use a thick rubber glove or some other non-conducting item to hold it!). If it does not spark, you've got a wire disconnected somewhere, or maybe a bad coil. If it does, then check for gasoline.
Of course, be sure you've got the wires in the right order. If it sounds like it's backfiring, you've got a wire (or two) in the wrong order.
