2005 Chevrolet Trailblazer Q&A

2005 Chevrolet Trailblazer Question: FUEL GAUGE

MY FUEL GAUGE DOES NOT REGISTER RIGHT, WHEN I FILL UP THE GAUGE STAYS ON EMPTY WITH LIGHT ON THEN GADUALLY MOVES TO FULL THEN BACK TO EMPTY AGAIN, THEN IT WILL REGISTER RIGHT UNTILL ABOUT A QUARTER OF A TANK AND THEN GO TO EMPTY AGAIN. IS THIS SOMTHING I CAN REPLACE MYSELF OR DO I HAVE TO TAKE TO A DEALER? -
Answer 1
My 05 Trailblazer did the same thing. It required pulling the fuel tank and replacing the fuel pump inside the tank. -
Answer 2
This is not uncommon with the Chevy Trailbalzer. It has happened to myself and 2 other owners that I personaly know. The cost to repair is $500. Should be a recall. I just make sure I fill up before I reach 300 miles to be safe. -
