I would start with a module. you'll have power at the coil regardless of the computer, thats a hard wire from the ignition. The ECM fuses are in the fuse box.

as far as I know the only thing that causes no spark and no injector pulse is the oil pressure sendor switch, when it goes bad or does not detect oil pressure more than 4psi it will not allow the motor to run or start. = no spark no fuel

but your injectors were dumping fuel to begin with and it was just a no spark prob which makes this one harder to diagnose.

have you taken the distributor cap off and made sure the camshaft is in-fact spinning the rotor button?
have you double checked the wiring inside the distributor, I bought a new one a few years back and the manufacture forgot to solder the one of pick up coil wires it was just hanging and making no contact and no vroom vroom.
