As the title states, my coil packs aren't getting power. I just swapped my stock DE with 180k on it because I got rod knock for a DE out of an 04 G35 with 86k I picked up at a junk yard. The motor ran before I plucked it out.

After swapping it in, it will crank but won't fire up. I know there is fuel and just to check to see if I messed up the timing I pulled out the crank sensor to see if it would start in limp mode, to no avail.

What are some reasons I wouldn't be getting spark? Could the coil packs have gone bad in transport or something of the sort?

 

are all the coil packs not getting voltage? Please tell us that you quadruple checked that you plugged the harness in?

 

I have looked at every wiring harness diagram for the de and I'm not seeing anything I would have missed unless I missed a random ground. None of my coil packs are getting power.

could a cam position sensor have gone bad? I know my ignition relay is working and that was my first suspicion.
