Hey guys,

I'm new to the CBR scene and I'm actually working on a friends bike, 2015 600rr. This bike has me completely lost.

Symptoms: no spark.
What I've done so far: new plugs, new coils. New ECU, ran continuity tests between the coils all the way back to the starter relay according to the shop manual, replaced the CKP and CMP sensors (both reading above 0.7v minimum voltage), bypassed and checked the BAS with no success...and yes, I've checked and charged the battery.

Everything is checking out, except for the spark. I have power going to the plugs, but when I turn the ignition, and kill switch on, it grounds out. The switch is the only thing i haven't checked yet for voltage, but when you turn it to "run" the BAS and starter relay all work.

Any help is appreciated.

Hi , just to be clear , you say with key in kill switch at run, the relays click and fuel pump runs, and when you press the start button it goes to ground, is that so?
