It must be more than just the fuel pump priming - the fuel pump could run continuously, but without the injectors firing you wouldn't get any fuel into the cylinders.
Thus it sounds like the ECU is running the fuel pump and firing the injectors - these are two separate outputs/actions - the later of which clearly it shouldn't be doing with the engine not turning and thus no timing signal from the CPS.
Is it doing this reliably enough that you can easily test and diagnose the issue, or is it intermittent?
You really need to get the PC connected so that you can see the live data readout from the ECU and see what it's doing.
