The pump is a like a buzzing sound - don't know what the whoosh could be?!
On the car I had the problem with, after checking that I had spark, I got some of that starter stuff in a can and sprayed it into the throat of the intake manifold (air cleaner was off, but you still need the little brown wired sensor in the end earthed on something) whislt another mate cranked it. The car would start (or try to start) briefly - that's how I knew that fuel was not getting to the engine.
Don't know what is the best course of action for your spark plug, but I doubt that would be the source of complete absence of signs of life. I would rather try to get the motor running as-is so you can check other things like oil pressure, compression, listen for knocks etc before worrying about fixing the spark plug.
Good luck, Drew
