You may have a faulty fuel sending unit and the bad news is, that unit is in the fuel tank. GM has had a problem with these units and many times this has been the fix. Buy 2 or 3 bottles of Techron. It is an additive for your fuel tank. It has cleaning agents that help remove the sulpher deposits which were corroding some of the fuel sending units in the tank. Run a few tankfulls of this thru your SUV. If your Trailblazer is out of warranty I would try this before anything.
Top Tier Gasolines:
There are certain brands of gas that have these cleaners (Techron) in them and if you could purchase a brand with this techron in it, it will save you from buying it separately and having to add it. GM has participated in this top tier gasoline research and redommends these fuels for your vehicle. If you can't find a company selling one of the top tier gasolines in yoru area you can always add the techron to keep your fuel sending until from the supher build up.
Chevy Recall:On 8/25/2011 Chevy finally released what they are calling a "Special Policy Coverage" exception/recall for select 2005 models for a known "premature fuel level sensor contact wear" issue. Recall good for select vehicles under 100k or 10 Years, whichever is first through 8/2014. Contact your Chevy service loaction wtih your vehicle VIN and you may qualify. My 2005 Trailblazer V8 qualified (10054B) and my appointment's next week for the repair. I share this because I've been battleing with Chevy for over 8 months now. I think it is a pretty pathetic showing for the Service center not to have reached out to me. I had been checking in periodically for an update on the recall.
