So... progress. I cant tell you how many times I read the theory of the system. Not an expert but I think I understand what to measure and expect. But it wasnt working as expected. Maybe grasping I swapped the connectors for the crank sensors. And it started right up and ran. So chasing my tail turns out to be a preexisting condition I wasnt expecting.

But now its running rich. It idles a little rough then when given full throttle it stumbles then black smoke. Maybe some fuel in the oil?

thanks again for your help, getting closer

Good progress.
I supppose the wires to the reference and speed sensor are the culprit(s). If one of them fails (reference sensor is only necessary for engine start!) engine won't start at all.

Black smoke is uberrich mixture, burnt oil looks blueish or grey...don't hink that so much fuel is in the engine oil. More likely there's still unburned fuel in the exhaust or so...

There may be still another problem, most likely an electricial issue. Keep that in mind, that two or more issues may interfere and mimic a complete different behaviour which may confuse you!
