2003 Grand Am wont start when its cold outside

[Ron21]

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

How old are the plugs ?

It also could be a vacum leak right off the intake.

check your coolant level,

also you can try disconnecting your ect sensor and measure the resistance the ect is reading in the morning, then measure the water temperature. I will find specs for you and then you can compare it. Also did you gap sparkplugs? Also clean throttle body and iac passages

Also might check your fuel pressure cold then again when its hot to see if the pumps building enough pressure cold.
