I think your battery's flat... new, powerful etc - ok fair enough... but you've cranked it heaps of times... usually if you crank it like 20 times over, say, a period of 20 mins or so, the battery will die so try connecting a jumper lead to it with another car and jump start it.
Also check all your hoses - a hose leak, say, to your BOV will prevent the car from starting up... check your exhaust piping and finally check your spark plugs... try this first then come back and I'm sure someone from here will be able to give you more suggestions.
Good luck!
