Help please, Johnson 200hp firing issue

Hello All,
Please give me some tips if you have anything on mind or have experienced this type of problem:
'99 Model Johnson 200hp Venom is not firing right. It's getting spark at #1, #3, #4 & #6. I changed out the stator and it's doing the same. I put on a new powerpack and it's now getting only #1&#3. The other bank went dead. I put in another used pp and it's firing differently.
Did a DVA test and stator seems to be ok. Put on new timing plate sensor and pp and it's changing. But still I don't get all 6cylinder fire.
What's the potential cause, please? No short in key ignition, no voltage to kill wire, all groundings look good...
Any tip or comment is deeply appreciated.

Have ya'll seen this?

I think my motor is having this kind of firing order? Has anyone here or over the world encountered?

Old stator, old timer base, old pack, I am back to square one = only #1, #3, #4, #6. Old stator, new timer base, new power pack =#1 and #3 only. ???
