Hi Everyone. Seems to be a growing trend. I have a 2000 S-10 4.3L Blazer 4x4 and its giving me trouble on cold mornings as well. I get a spin no start sometimes and nothing others. I've been to the dealer and they replaced the fuel pump but I'm still getting problems. But I've noticed that its only on mornings that are below 32. I've tried dumping a can of gas treatment in thinking it was a frozen gas line, but still no help. The last few times I could get it started was to try cranking, waiting 2 mins, cranking waiting 5 mins, then cranking again. I'm going to have to take back to the dealer soon, anyone have any updates on this common problem?
