How are you sure its in open loop? Do you have a scantool with the ability to tell you so?

If it is going into open loop and staying there it will be ignoring the O2 sensors completely and running purely off predetermined tables. This is what you must find out. I still think you need to verify your powers and grounds to the ECU.
