multiple cilynder ignition malfunction p0300

[winy]

i folks ,

I've changed myself the right head cilynder (1,3,5 cilynders bank#1) couple days ago and my car is not working properly. the code reader shows "multiple cilynder ignition malfunction"(p0300). I setted the timing belt like in the manual. everything seems it's in his place but I got no sparks on 2,4,6 cilynders spark-plugs 1,3,5 are working. When I get out the coil 1,2,3 the cilynders 2,4,6 start to work. can you tell what's wrong and how can I fix it?

I have a 2000 amigo, i got the same code sometime and then it stopped. Recently i changed all spark plugs and got the same code back. Don't know what could be the problem.
Did you resolve the problem
