I do have some questions though, where do the injector wires plug back into the ECM? If I ever had to replace the entire loom to the injectors what kind of work/parts would I be looking at?

I think you would need the whole engine harness but there's nothing wrong with cutting an injector plug off of a junkyard donor.


Looks like you found the problem.
