Check for power at the pos side of the injectors.
If you are getting power to the ECU , crack it open, follow pins to the power to the board check for power / ground. There should be a voltage regulator, largish capacitor and MOV inside, check for power here.

Yes, power is present, but no modulated ground signal...
