When you crank the starter does the tach jump or stay dead? That's a dumb little trick from my C900 days... and I'm only guessing that those particular 'features' are the same.
If the ECU doesn't get a tachometer signal from the ignition, it won't fire the injectors, and it'll shut off the fuel pump within a couple seconds. +12v at the injectors is always present with the key on, the ECU closes the ground leg of their circuit to fire them.
You say you have +12v at the DI, but it might be an open circuit from there back to the ECU. Unfortunately, I don't have any circuit drawings for our '01.
