Ive seen the injector open fault several times on perfectly fine running quads. I seriously doubt injectors will ever fail. Im not sure if it was a glitch in the program or not. One thing that might be a possible cause for a no start condiition is a bad flywheel crank bearing. The flywheel will flop around giving faulty crank sensor signals which lead to intermittant spark and fuel spray. It can be easily checked by removing the flywheel cover and gently prying up and down on the flywheel. It shouldnt move much at all. A dead givaway is oil and metal shavings all over the housing. This was a common problem with the early cast case motors . The starter also grinds a little louder while cranking. Just something easy to check.
