Electrical problem
1986 Chevy Astro 6 cyl Two Wheel Drive Automatic 150k miles

There isn't any electricity at the fuel injectors? I have checked all fuses- they are good. I have also replaced fuel pump relay and ignition control module. Oh and also replaced fuel pump. I also have put a used ecm/computer in van. Still there isn't any spark at injectors? Should both sides of injector be hot?? Can you help me out with any ideas? Thanks

When key at run one of the injector wire should be hot-if you're getting power to the injector and its not pulsing could be the computer ground drivers-also test the injector/s
