Code P0353 Help! So I have a code P0353 for Cylinder 3 Coil Pack Secondary Circuit Malfunction. I have swapped coils from 1 to 3, cleared code, road tested, no success. I recently got a MSD 2-Step installed into the car which runs off a switch inside of the car that I hold. I thought well hey, the 2-Step is integrated into the coil pack harness so maybe that is what is causing the issue. I disconnected this & cleared so I could road test again. The light has re-illuminated. Same code also, P0353. I checked the wires, nothing is broken & no pins are damaged. My hunch is that it could be the coil pack wiring harness perhaps? Has anyone ever experienced this or had any luck by doing that with this specific code?
My car is a 2002 Z28 with a LS1 engine that is Cam & Intake. Any help would be really appreciated!!

i would switch plug wire around see what happens. dont change check with spark checker light between plug and wire. lights up spark there probably something going on with the injector or compression problem. i had a yukon that kept getting misfires on 4 & 7. put new plugs/wires on same. changed plugs same. try another set injectors same thing. ended up pulling intake. found the rubbers around holes on gaskets cracked. new intake gaskets fixed it.
