The common one is the fuel pump. When you turn the ignition on you should hear it while as it builds pressure (its in the tank behind the seat) in the rail and then with off. If it's silent then it's pump related (a simple fix). If you have a Schrader pressure tester you can measure it above the throttle body - it should be around 60 PSI
Assuming the fuel pump pumps then I would pull one of the spark plug leads off and hang a spark plug on the lead and crank it with the body of the plug agains the engine. If there is a spark then it's not coil pack, crank sensor etc. If there is a spark then throw a good dose of quick start into the throttle body and crank it - see if it catches.
You could put it into gear and rock it to get the crank dots to line up - you should see the little dots lined up (just make sure you take it out of gear before you crank again) - I doubt very much its this.
Fuel vapour is massively explosive so if it has fuel and spark you will get something!
Ive done over 50,000 miles with this and come across most issues - all long term fixed now
Report back your findings and we can make some more suggestions - good luck!
