Is number 5 plug wet after running it a little while? If it's not firing and the plug is wet, then you can be reasonably assured that it's getting fuel. If it's dry, it's either firing or not getting fuel. Any possibility of a plugged intake port? Maybe an errant shop towel or something? Fact is, if the other cylinders are firing and you have compression and ignition, the only thing missing is fuel. That said, I have seen coils that would spark outside of the cylinder but not produce enough spark under compression to ignite the mixture. I'm not one to throw parts at a problem, but for the price of a coil, it might be worth a shot.
