Misfire!

alright i was recently going through a problem with rough idle, running rich, stalling out and all that good stuff.

Ended up having an air leak, my intercooler was cracked so the maf was not reading right causing the engine to throw fuel with less air (just in case someone is going through that problem check air leaks and also injector o rings)

but anwho that was solved but second problem is the miss fire. i have no spark on my third cylinder. The coil pack is fine i need to trace the wire down up to the ECU.

How do i test the ignition chip and/or ecu?
