Okay, I found no voltage at the plug on the idle control valve, because there was no voltage at the supply to the idle control unit. The search goes on. I can only lay on my back under the dash for so long.

I do understand the airflow sensor plate, and now the idle air valve, but where does the idle FUEL come from? Is it ported through the idle air distributor? There is a fuel line connected there through the cold start valve, and air pipes running to the injectors, but I couldn't find much of an explanation in the manual. How does idle fuel get metered?
Thanks again for any help.
