As I was getting ready to reply Zenith gave me a callback, they are pretty darn awesome. He explained how the entire fuel system worked down to the details. The injector ground is pulsed to make the injector fire, you can see on the wavelength that when it surges the ground pulse is significantly shorter than when it fires correctly. Their tech confirmed with that information plus the 0.5ohm reading that the injector coil is faulty.
