Technician A says that on EHI systems the ECM sends an electrical signal to the EHI to close the solenoid valve when fuel injection is requested. Technician B says that on EHI systems the ECM always applies power to the injector and disconnects the electrical signal to “pulse-fire” the injector. Who is correct?
