#12 of 24 04 trailblazer gas smell
Nov 26, 2011 (7:51 am)
I too have a smell of gas coming from somewhere under the truck. A code can up for p0128 but that is for Thermo temp and should have nithng to do with the smell. If I take off the air cleaner I get a real strong odor of fuel. Any suggestions?

On mine the fuel pump canister on the top of the fuel tank had rusted out. At 1st no leak was apparent by a puddle on the ground only the odor and I thought the fuel cap might have been defective. After about 2 weeks drips on the ground became noticeable. I understand this is a common condition especially if the vehicle is operated in northern states and winter conditions where roads are heavily salted. In my case this was covered under the emissions control warranty which is over and above the standard warranty, 80K miles if I remember correctly. If this applies to you you may have to dispute this with your dealer as they don't seem to always offer this info. The cost of the job can run in the $600 - $800 range if I remember correctly. Good luck!
#14 of 24 04 Trailblazer, Gas smell/noisy Exhasust/1&2 ignition coils keeps going out

I have replaced all 6 of the ignition coils in my truck at least twice now, but I'm having to replace the number 1 and 2, constantly, my truck will run for a month tops, and then the smell starts getting stronger, the exhaust gets louder, and one of the ignition coils has went out. Has anyone else had a problem with their ignition coils.

I have the gas smell and found a notice for it saying it was covered to 150,000 miles, but amazingly my VIN is only covered to 120,000 miles. I have 121,768. GM sucks. Why are cars covered for different mileage amounts?

2004 Chevy Trailblazer EXT, 4WD. I smell gas coming in through the vents. The smell seems stronger when the vehicle is just sitting and or when I put gas in the tank. I have also noticed that the exhaust just keeps getting louder. It seems to be the loudest when sitting in the front, passenger seat. Any ideas on what this could be? Is there a recall in NJ? Any thoughts or ideas would be appreciated. Thank you!
#20 of 24 Smell of Gasoline under the hood
Feb 10, 2013 (3:50 am)
I have a 2004 Chevrolet Trailblazer LT. I have just recently started smelling gas under the hood. The odor is strongest when I am just sitting at idle, or maybe that is when I start to smell it the most. There is also a clicking noise, which resembles the noise that a tensioner gives. I had it replaced last summer, when I returned from a tour in Afghanistan, and then a week later, it starting clicking again. Now I have the odor of gas coming out from the hood. The smell is strongest on the passenger side. I bought my truck in VA in Sept. 2008, and now I live in Georgia. I dont know what is going on here. I love this truck. Can someone give me some insight on this please. Thank you.
