Help Desperately Needed! Cylinder 2 Not Firing!

[R31vhead]

I own an R31 with a recently installed RB20. Cylinder 2 is not firing for some reason. My only clue is that coil #2 is getting much hotter than the others, so it is obviously getting constant signal instead of a pulse. I have replaced ignitor box, the coil (which had burst open from the heat), the wiring that joins the coils to the ignitor box, and spark plugs. After all that it still does it, and I'm now stumped for ideas.

Does anyone here have some suggestions where to look next?

Check the wiring between the ignitor and the ecu for shorts possibly.

Check that the output signal at the ecu is correct (or swap ecus with someone who has the same engine).

Check for error codes on the ecu.

Wire up a consult plug and visit your friendly local Nissan workshop for a check.
