98 buick I show no secondary waveforms on the odd cylinders. I’m using a hantek 8000c. The even cylinders show a normal secondary waveform. I am lost.

On this engine, you have a waste-spark ignition system. Half of the coils are being fired negatively whereas the other half are being fired positively. You’ll want to invert the waveforms which you can’t see.
