Has anyone else had this problem or know what the problem could be. My van starts find until winter comes. In the cold weather it always starts first thing and than I will drive to the store and come out to leave about 10mins and the van will not start. It turns over, sounds like gas is not getting through. I have had the ignition wire changed and now this is my second winter with the van. I was left 3 times last year, I got to the point where I did not turn the van off when I went to the store. Now the problem has resurfaced again. No help from my dealer. They say they can not find the problem. Never will I buy a gm again. Anyone have some helpful advice.
