2000 isuzu rodeo 3.2 v6 dohc p0300? LOST!!!!!!!

i replaced the heads on my rodeo due to cams locking up in them, after the replacement i figured i would change the timing belt and plugs. usual stuff. after everything is put back together, the engine has really rough idle, codes p0300 and when the coil packs were checked to see if they were firing, the plugs on drivers side will not fire? i was told the # 6 coil pack is "specific" and must go in the# 6 cylender. any help is greatly appreciated!
