So, the cooling fan in the Sunfire doesn't want to turn on.....

I know the PCM is getting a temp signal (get a reading with HPT), and even turning the fan turn on temp to 150* doesn't get it to kick on.

The run-on with key off works though (180 sec if over 175*)

Anyone think there will be an issue piggybacking this with the stock wiring so the run-on function still works (I plan on turning up the fan turn on temp in the PCM to 255* and let the Spal unit control the fan)?
