DBW not working, troubleshooting?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 2001 5.3 with DBW, and we have gotten it to fire up, but we are getting zero response from the fuel pedal. Is there a way to test any of the plugs on the throttle body, fuel pedal, or TAC module to trouble shoot what could be the problem? I see on the schematics that some wires are 5v reference, is there a way to test any of these? Any help would be greatly appreciated
