no spark on two cylinders on Subaru?

i'm working on a subaru 2009 legacy outback 2.5 L and has spark only on cylikders #1 and #2, removed the connector at the coil and there is B+ on the center , one wire has blinking ground but the other has nothing, checked the igniter and has blinking in one wire from ecm but ground on the other two from the ecm, I don't know how the system works, need your help, thank you
