No Spark on Cyl 2 &3

[NVRL8TE]

Team,

I have completed an under the plenum service.

All new D545 Ac Delco coils, and cyl 2 and 3 do not fire.

I took it back apart, and the coil tests good on the primary, and secondary, and the INJ1 fuse is good.

What else besides the coil can cause this?

Thanks in advance!
