With key on I have power to the coil 15, and so far all checks indicate
things are as they should be.  Yet when the starter is engaged, I get no
spark - using a grounded plug on #1 wire to test and the fuel pump does not
turn on.  What is the trigger for the pump?

The trigger for the pump is the switching signal for the ignition. It is
done that way for safety. If you are missing that signal, that is why you
have no spark and no fuel. You have to find out where that signal is being
dropped. There are two wires going to the coil, and the one not to term 15
is the one you need to check. I'm not sure if the turbos still have the ICU,
but if it does, check for power going to it. It doesn't rely on its mounting
for ground, FYI.

This is about as far as I can go without being there with schematics, hope
it helps.
