#6 Coil not firing..

[Ironhydroxide]

I am stumped on this...

My #6 coil isn't firing (checked with method of pulling injector leads as well as no-touch temp check on all the exhaust manifolds. The #6 is MUCH colder than all the others) Every other coil is firing. Also, I can hear (with a mechanics stethoscope) each injector clicking. The coil itself is good (checked with spark tester when connected to a different coil lead), I've traced all the wires, from the Coil to the Ignitor (good) as well as all 7 wires from the Ignitor to the ECU (good).

The only code I get when checking codes (after a clear and about a day or so of driving) is 55 (EGR Temp sensor fault)

beyond that. I'm stumped. Unless the Ignitor is bad, (and sadly I don't have a replacement for it)

Ideas anyone?

thanks in advance for replies.
