2006 Pontiac G6 replace ECM question!
I have situation where my 2006 G6 will stall while driving. You wait 2 to 8 hours and it runs again until next stall. While in no crank condition it does have proper fuel pressure but no fire. It never provides any codes while trying to start the car. I have concluded its a possible bad ECM. I received a new ECM which was set for my particular VIN #. My understanding is the only thing i need to do is perform the PK3 + key learn procedure but I cannot get it to work. I let it set for the 10 to 15 min and security light never goes off. I also notice where the mileage would be displayed it says "error" The old ECM starts fine. I am to the point of taking it to the dealer……What am I missing? Thanks in advance for any help!
