1991 Hyundai Excel Question: 91 excel injectors sensor

I am working on a 91 excel, the fuel pump is running and I have gas after the filter to the injectors but I am not getting 12 volts to open the injectors? Where is the sensor and what sends voltage to energize the injectors. mrmopar440@hotmail.com -

12 from ignition switch is constant with key on. the ground is controlled by ecm.it looks at the crank sensor for a trigger. you might want to start there. Roy -
