How to Diagnose Flex Fuel Sensor.....
Have an 05 6.0 with factory ecm. Running the GM 13577379 Flex Fuel sensor. Sensor has 12V going to it, ground is good. Wire is ran to I think it was Pin 25 on the blue connector on the ECM. I am running E85 and it reads 0% Ethanol content. Am I hooked into the wrong pin? Or how do you test this sensor? Thanks

If you've added the sensor and haven't had it tuned, I'll just about guarantee you it's disabled in the tune.
Quite common with Gen3.
