okay.. there are 2 grounds OUT of the ECM, one right, one left. both tie together to one ground lug. somewhere from the tied point to ground the line was open. I tapped a new wire in and grounded it that fixed the O2 issue.

with no ground from the ECM for the O2 s I was reading .45v ALL the time on BOTH sensors
