having a problem with the injectors getting them fire. I had one bad injector pulled the rail replaced the injector with a known good one put it back together and I got no fire to the injectors clean the grounds straps check the power stage, check the ballast resistor, still not working right I swapped out a computer that didn't change anything if I crank it and hit the green wires on the ballast resistor you can hear the injectors pulsing something in the system's not grounding the fuel injectors any ideas
