Well, I'll give it my shot. I'd be concerned about the hydrogenated oil, but I don't think there is any wax in it, unless you mixed it with diesel. Is the wvo returning to the diesel tank? That's where you may get wax.

I have run 7000 miles on completely unheated wvo with only minor injector coking issues. Injector coking is more likely to be from shutting down on wvo than starting on it as the oil polymerizes on the wet tip. Ring land coking is more likely to be caused by starting on cold wvo.

But, if you are not getting even a quiver from starting fluid, it would seem like either:
a) there is an obstruction in the intake somewhere
b) the valve timing is way off
c) there is no compression at all.

When cranking the engine, see if the exhaust is pulsing air out. Using starter fluid, you ought to be able to smell it at the exhaust if it doesn't get burned.

A compression test will likely point you in the right direction.

Good luck and keep us posted.
