no Sparkplug firing at Cylinder 8 & 9

[Matrix]

I have a 2006 SRT10 vert. Cylinder 8+9 is not firing. The PCM code is P0353 (ignition coil circuit 3). I´ve changed the 6-plug coil and the 4-plug coil, also the ignition wires at cylinder 8 & 9, same problem. The spark plugs don´t fire at cylinder 8 + 9. Have anyone an idea what the problem is?

Thanks for the help

Defective coil drive IGBT [Isolated Gate Bipolar Transistor, or Coil Driver] or broken wire from Coil to PCM connector. Check continuity between coil connector and PCM. If OK, replace PCM.
