it makes sense

about the sparking isn't the ECU that signals the ignition amplifier module to spark?

could any of the initial problem (1 tooth out of pulley and big misfire) be the cause to a broken ECU?

I know that the initial problem is very unlikely to happen, but the fact is that is the only explanation to the alternator venting blades not in place and the pulley tooth wenting way

even so, I had 3 or 4 times sparks on all plugs and it didn't started anyway. at this moment it sparks well and some other times it does not.

What I'm going to do is getting a completly new alternator (on monday) and try again, as it's the only thing I had not changed yet.

btw can the ignition relay the cause for sparking problems? (I was told that is one of the big ones inside fuse box. I didn't change any of these relays as they were "clicking" and so)
