I know you're going to debate this until you get the last word but he had already swapped injectors and the cylinder he moved the injector to had no problem so he already eliminated injector shorts and the test clearly showed the driver was dead right from initial cranking. He had also already backprobed right at the ECM so it didn't have a broken wire either.

I'm not debating. I'm just hopefully opening the eyes to technicians and others about troubleshooting. Any monkey can follow a flow chart, but the ones that widen their horizons to understand circuit design and think about all the possibilities that could happen in a particular situation and understand how to eliminate each possibility until the actual culprit is determined are the ones that are valuable in the field.
You could cut that flow chart down to 4 easy steps, when Joe blow in the next bay is racking his brains with a vehicle all ripped apart ohm checking wires praying the flow chart god is there to save his soul.

Sorry it took so long to return with the repair to my problem.Replacing The PCM repaired my problem. I made the mistake of trying a used PCM from a salvage yard. BIG MISTAKE ! Tried this two times,took it to a dealer to have it programed, failed twice never again, always buy a new one. Thanks again for all your help.
