I have a 2003 Grand Am with the 2.2 L. When it is cold outside the car will not start. After warming up in the sun the car starts right up and runs fine. Any idea what would be causing this

does it start and then stall? you could go to a local auto parts store and have them test the battery for free takes about 10 minutes

ok sounds like something wrong with the computer system when your car first starts up the engine enters a closed loop system it guesses how much fuel to give the engine until the sensors warmup and it gives out the exact amount but i have no clue on the problem

I have a 2003 Grand Am - 2.2 L and when it gets to negative double digits, it won't start. The first time, I had it towed to a garage. The mechanic said once it warmed up, it started fine. Today is the third time this has happened. I know it's not the batter because I bought a new one, just in case. A retired mechanic told me he believes a sensor could be going bad and when it's extremely cold, just won't start and told me about this closed loop thing. I believe he suggested having the crank or cam sensor checked, but I can just see it now - a female enters a shop and says she thinks the crank or cam sensor is bad, they won't listen to me. Guys at work still tell me it's the battery.
