CarComplaints.com Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.
This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.
Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

Most Common Solutions:
replace 6 coils and plugs and install addl weather strip (1 reports)
There is a notch in the center of the gutter lip under the weather strip. When it rained heavily and vehiclewas parked downhill, water went under weather strip and dripped on value cover and because of the overhead cam, it became a swimming pool. After a while there was a high water mark on the coils and corrosion which caused the arc of the spark plugs causing misfiring of the cylinders. Had to replace all coils and plug. Installed a cut-out heater hose over the entire weather strip and notch in the channel.
If the notch was not there, the water would not have gone into the value cover swimming hole.
