Hey Guys .Im new to this site and i would really like some help before returning to dealer. I have a 2002 Deville DTS and when it is real cold out i have trouble starting it . I crank it and it shut off like it is not getting gas and sometimes it will crank but it idle real low then shut off. I have to press the gas to get it going for about 45 seconds. I have no problem with it once it warms up or if is is warm outside. Does anyone know what this problem could be.
