It now makes sense to me that the noid light test showed nothing. After putting in new injector I did the noid light test again (just to satisfy my curiosity about what the noid light should do) and it did the flashing light as I believe it should. So, yes , I believe that injector was shorted out and it caused all injectors to have a dead circuit and therefore no pulse. Honestly, I really don't quite understand that . I don't have very good grasp on auto electronic systems. I felt very fortunate to have blundered on to what was causing the problem and am thankful I was able to fix it. Hope these posts may help someone else if they ever have a similar problem.
