Phil,
    I agree, it is pretty suspicious that both injectors failed at the same
time.  I would unplug the ECU and test the injector resistance back through
the harness. Unplug them one at a time and watch for a change in resistance.
I suspect a broken wire.
     FYI all injectors are fired at the same time so they must be connected
in parallel. I do not know if this is done in the wiring or the ECU.
