was wondering ... on my 1998 GTP ... exchanged the S/C, hated that job.

Put everything together, and have not been able to start it, info from our friends on this group brought to my attention, maybe plugs were wrong, being stubborn, I did not check that, finally today I did, and "YES" cyl 4 and 6 were mixed up.

Car turns over nicely, but will not start, did I do any damange?

I wouldn't think so. Check every thing over again to insure all connections are made.

Make sure the numbers on the coil packs are proper. It should be arranged like this..
