Its a 2004 Pontiac Grand AM it has 150k on it and is a V6 Yesterday i put a resistor behind the ignition for the yellow and black wires running into the BCM, I then checked the BCM i noticed a little corrosion on the right side of the connectors this was the grey middle connector the other two were fine, i then lubricated and cleaned the connectors and placed them back into the rightful positions. the car started however the security light is still on, and stated in my initial post, the car will start in the morning. with no problems or stall, after the car has sat for a while usually around 5pm the car will not say ANYTHING but EVERYTHING on the inside of the car lights up, i know if the car will start before hand if my remote unlock doesnt work. i believe when it is hot the plastic in the bcm expands and causes the disconnection. i usually have to leave my car at work get a ride the next morning and that morning it works fine.. just not in the afternoon.. please help me with this thanks
2004 Pontiac grand am V6 150k
I have already tried putting a dummy resistor in place where i cut the yellow and black wire behind the ignition, i also check the bcm with all three connections. the light grey middle connector had corrosion around the prongs on the right side. i lubricated them and cleaned and reinstalled them. i turned the car on it started however the security light is still on.as i stated in my initial post the car starts fine in the morning when its cooler. after sitting outside until 5pmit wont do ANYTHING but EVERYTHING on the inside lights up.i know when its not goin to work when my remote doesnt unlock the doors, THEN I HAVE NO CHOICE BUT TO LEAVE IT AT WORK i believe when it gets hot outside the plastic in the bcm expands causing the disconnection, because when i get to work in the morning i try to start it and it starts fine pleas help me with this issue and thanks in advanced
If you have completed the pass lock relearn procedure and verified the battery voltage is good then I too believe the failure is a bad BCM since the key fobs also fail at the same time.
Chris, after more research I've read that the "radiator reserve has an sensor when the car gets hot it shuts off the fuel ... could this be an possibility
Yes it can shut down the fuel of overheating r if there is a cooling system issue. If you have this warning showing up not prior mentioned then yes, do resolve this concern first.
