Hello,
Have a 2018 jet tender with a rotax 900 will crank but not fire.
Ha e checked the following
1 solenoid good
2 both relays good ( replaces with new
3 have 12 v olts at. Coils and. Injectors
4 checked wire harness from Ecm to coils and injectors all ohms are good
5 checked the. Ground bus prior to Ecm( all good)

I am not getting. Any continuity to ground at the coils or the injectors but I am getting the 12 volts there are no codes shown.
I am not getting any spark with coil and plug removed. And grounded during crank any help would be great thanks
 
Is your throttle in neutral? Usually this produces a no crank situation. Is the kill switch key w/ lanyard in the kill switch? Looking online I see you have one.

Yes. throttle assembly is new. With a new neutral switch and the kill switch is operating as should.
It will crank just fine just a no fire situation.

Thanks for the reply any help is appreciated
