After 2 revs, the only synch signal is coming from the crank sensor. Time to go into PCM diagnostics.
It could be that the CKP signal could go to 5V if it was slightly closer to the high spot on the cam. The spacer that came with a new ones were just about the same thickness as a manila file folder. But as hard as they are to come by, it isn't worth the risk.The cam sensor signal was almost a perfect square wave, 0 & 4V. The crank sensor signal has pairs of pulses, caused by the 54 then 90 degree separation of the cylinder firings. I didn't take a long enough sample to see a whole 720 degrees, but it's really likely that it's working right. I'll get a full 720 degree sample anyway...
