No voltage to fuel injectors 700 1988

My fuel injectors are grounded well but I am not getting any voltage to them. As there are only 2 wires to each injector, and the ground is pulsed by the ECU, is my problem in the ECU or elsewhere? Any ideas on how I determine this?
Thanks for your time in this...

    Besides Randy's tip, check the fuse 1, and then the Fuel Injection Relay. The Fuel Injection Relay is a well known source of trouble. Use a magnifying lens to look at the solder joints on the printed circuit board. Re-solder as necessary. There are great instructions in the 700/900 FAQ for this.

    Check the radio suppression relay. Probably black and mounted on the strut tower under the hood. They are the ones sealed with silicone (along with the fan relay) If you find two identicle relays in the area, swap them for each other and try again. If it starts resolder both of them (circuit boards) and you should be good to go.

    The ECU in your car is fairly reliable but I one go bad and it would not fire the injectors.
