plug it in and crank it over, injectors and fuel pump work, still no spark,

I don't have much time on 700/900 cars and none with your '87 PRV. But that condition sounds like some early (?) version of EZK, with a bad final amplifier (aka "power stage") that does the Coil minus triggering.

We've had a rare 1 or 2 like that here — the only case I know of where the ignition is good up to and including the ICU, which then tells the Fuel ECU to go ahead. Thus giving you fuel but no spark.

Maybe some one with more late '80s 700 knowledge will ring in...
