This is my first time posting here. Hopfully someome can help me out. I have a 250 trailblazer. It will start up fine when it is cold and runs fine. But when we shut it down it will not start back up. If we let it sit for a hour or so it fires back up. I have cleaned out the carb and check out the filter and it will run fine for about a day then the same thing happens again. I have taken it to the shop and they did the same thing with the same results. Maybe someone can give me some input and let me know if you had the same prob. Thanks for your help, Mud jumper[img]i/expressions/face-icon-small-confused.gif[/img]

 

Hello mudjumper. I have two Trailblazers and I have not seen this problem with either. When it happens, did you check the spark to see if it is ok? Also, can you pull start it when this happens? I have read in another post of a similar problem. He was able to pull start it when the electric start would not start it. Let us know if this is the case. Oh, and welcome to the forums.
I hope this helps you [img]i/expressions/face-icon-small-smile.gif[/img]
