Let me re-start this. My CEL is ringin off the hook, my OBD is DOA, That's 1st, then I have injector issues.

I need a bit of guidance on the OBD. There's power at the port, my ULTRA GAUGE lites, just no readings. Savannah pointed my at a header under the glove box I couldn;t identify the lavender #20 lead or the #16, I believe those are the #'s. That's where I'm stalled.
So any enlightened comments would be greatly appreciated.
Thanks
