Ignition driver born not working

Ok, how are you testing?  Have you disconnected all wiring and checking directly at ECU pin with an LED test light or oscilloscope? 

Potentially something internal is damaged, but ignition drive 5-8 are all done with the same chip, so usually if the chip fails you will have 4 ignition drives that dont work.  So I suggest you need to eliminate as many other external possibilities as you can before sending the ecu in for inspection.
