Default F4i won't fire

Cbr600f4i won't fire.. bike was running good until laid over on the clutch basket side and cracked the case and I repaired it until I buy a new one.. I've replaced pulse sensor. fuel pump primes. BAS bypassed clutch switch bypassed. It will turn over all day long but won't spark i've got 12v on one side of the ignition coil plugs but only 3 or 4v on the other? The diode in the ignition was blown but I took a 9v battery and hooked the pink wire to it to bypass it just to see if it would run and still won't fire.... Only thing I can think of is ECU PLEASE HELPPPPP!!!!!!

Could you have put the pulse sensor on backwards?

That looks right. Did anything with the exciter ring get bent or damaged? Are all your grounds good? I think there is a ground on the left neck of the frame that needs to be there.

When you say Exciter ring are you talking about the star like gear I guess you'd call it that the sensor reads? Btw thanks for the help

Yes. The sensor and ring need to be lined up to work.
