Have you verified the distributor is spinning and therefore the timing belt isn't broken?
For the optical distributor diagnosis, I'd look here:
Yes, the distributor is turning. The timing belt is not broken. The link provided a procedure for checking the pickup. The pickup appears to be bad because it does not switch between 0 and 5V. Because I live in southern Utah, I have to wait for the next wagon train to get a replacement (tomorrow), so I'll let you know if that does the trick. Thanks for the help!

I know that's what the book says, but I measured nothing on the positive side of the coil whether cranking or not. I also didn't have a way to access the computer to see if there were any error codes.

On these cars, when the ignition is on, there is always steady 12V at the positive primary coil terminal, and the negative terminal gets switched on and off while firing.
It's a moot point, however, because valiant 67 and you provided enough information to steer me in the right direction. After replacing the ignition pickup (which arrived on this morning's Wells Fargo stage), this money pit started right up and is purring like a kitten. Much MUCH thanks to you guys for your help. It is genuinely appreciated.
