Get some Quick Start(ether) or some gas in a spray bottle.
Pull off the big air tube on the front of the intake, open throttle and spray fuel/ether into the intake.
Replace the tube, you don't need to tighten it.
Try to start engine.

If it fires up and dies you have spark but no fuel from injectors
If it doesn't fire then you have no spark

So a good quick 50/50 test

Report back to diagnose spark or fuel issue
