    Last thing I would check would be the resistance of the wiring from the Injector pigtail to the pin on the computer, and also check the ECU ground.

    Ok folks hears the latest,
    You know I went to dealer got a new pcm of coarse they had to install $85 , they had to program $115,after all that came home with the same problem no pulse from pcm to injector num 6 ,dealer wanted to scedule me for more diagnostics $$$$$$$$$$$$$$$. I’m thinking no diag. had already been made, no pulse from pcm throgh circuit to injector num 6. My decision was to purchase another pcm from Flagship 1. Installed it and problems went away. Took dealer pcm back for $ return, long story short I have a 1000 dollor paperweight.

    I was told by Flagship one that the chances of the new dealer pcm having the same code as the old pcm would be like less likely than winning the lottory providing there were no mechanical issues, well flagship pcm fix my problem.

    To go along with last post, In my investigation , with the right programing equipment you can turn off components at will,, injectors etc. Stating to smell a little swampy in the Dealership
