1991 Hyundai Excel Question: 91 excel injectors sensor



caleb440, 1.5L 4 Cylinder, Tioga, ND, June 13, 2010, 21:06

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.

    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.
