2003 Chevrolet Blazer Owner Comments

problem #1

Oct 012007

Blazer 6 cyl

  • Automatic transmission
  • 30,000 miles


vehicle decides when it wants to start. It's not the battery or starter. Maybe a vehicle computer problem. I saw someone else post the same problem. It won't start then if you wait 10 or 20 minutes it fires up like nothing ever happened. Never know when this is going to happen. The other day I stopped at a business 50 miles from my home, went back out and the vehicle wouldn't start. This time I had wait 4 hours before it would start. Too far from anyone I knew to call for help or a ride. There is nothing anyone can do so calling the autoclub is pointless. I continually tried to start it. After 4 hours or so it fired right up. This might happen once a month or once every 2 weeks. There seems to be no rhyme or reason for when or why it does it. Really frustrating to go to the grocery store or gas station and not know if it is going to start when you come out. Had it put on an analyzer, nothing shows up. Afraid to go to dealer ship, spend a lot of money, have them tell me they fixed it and get back on the road and find out they haven't. Talked to a chevy dealer in the area. They didn't seem like they were in a hurry to take it on. I've seen all the problems people have with these trailblazers that the dealer really can't seem to fix. I'm at my wits end. What do I do? I live in northern Wis. If this happens at the wrong place and time I could freeze to death.
