flex fuel issues

has anyone ever had the issue that the flex fuel module doesn't have the green light on as if there's no power going to the module? just rebuilt my motor but now having issues with either the module or sensor is my guess, looking at the live data its showing either 0% or 2% ethanol content. even though I have half a tank of fuel and its all e85. car is supercharged with the JR C38 kit. is there any good way to at least test for power, I assume it comes from the 02 sensor but curious if anyone knows for sure. my other option is to take the kit off and send it back to delicious, but I also don't want to deal with the wait time in doing so. Vehicles already been down for multiple months and I want to finally get it up and going again. My other thought is to drain the tank and just dump in some 91, take off the sensor and hope that the car will still actually run properly without the sensor even though the car is tuned to have the ethanol content accounted for.
