Is this coil on plug?
Customer: replied 2 years ago.
I don't have a way to get the codes right now. The coils are on the plug
Expert:  Mike S. replied 2 years ago.
Ok, with the key on run, do you have voltage going to all of the coils? The dark green/light green wires.
Expert:  Mike S. replied 2 years ago.
If nothing check Fuse S, fuse N and fuse W in the pdc.
Customer: replied 2 years ago.
I just checked my codes none appeared and my engine light is on and it blinked 10 times. We are having a pretty bad storm I will check fuses tomorrow.
Expert:  Mike S. replied 2 years ago.

Ok here are 2 wiring diagrams, click here.

The 2nd is 3 combinned and the other shows the ign coil drivers. They call ign #1 driver pin K19 in the test, but I believe it is actually K91 in the diagram.
