no spark from 3&6 on coil pack replaced coil pack still no spark from 3&6

'IF' testing was performed 'directly' at the coil tower with no spark... Open switching circuit from the PCM to coil pack.. OR .. PCM failure, which would be the least likely of the two!!!... That is the 'black wire' that's right next to the 'red wire' in the (4 wire) coil pack connector!!... For more info on testing, you need a repair manual or for a fee... www.alldatadiy.com... This is not for a novice or casual Diy'er!! ..You either one??
