And one more wrinkle: I opened up my rear seat panel and discovered that the bolt on the stud for the big wire into the starter was... kind of loose.
It looks like the stud is also a feed for five 12V feeds headed back toward the engine compartment - 1 thick, 1 thin and 3 medium red wires. I cleaned everything up, tightened the bolt down, and (here we go again -- it's like dating a German chick) the engine started right up.
It's started three times in a row, now.
So it could be that the movement there was interrupting/restoring power to downtream stuff and could have been messing with one loop or another in my startup symphony. Or not. The thing with an intermittent failure is, well... it's intermittent.
But the whole problem has cycled through pretty reliably before, so I'll keep testing the thing to see if I should go ahead and order a new crank position sensor or if I'm done and the old mongrel is good again.
Stay tuned for more.
