It looks to be attached to the side of the tank behind the sheild. It looks as though there is an access cover to get to it.There should be a skid plate, or sheild bolted to the tank brackets.

Where is the fuel filter located on a 04 sedona

No external filter used on your model.
Most companies stopped using filters in 2001.
There is a screen at the end of the fuel pump in the tank but not normally replaced.

How to change fule filter 2006 gmc envoy 4.2 inline 6 moter

OUCH! I have an 06 also. The filter is located INSIDE the gas tank on the fuel pump. We do not have an external fuel filter like earlier years of Envoys and Trailblazers do. My 04' has one outside the frame rail. But 06' is in the tank.

Is there a fuel filter on this suv

Yes, if you didn't see it from the fuel lines coming from the tank along the frame rail, it's integrated into the fuel pump which is inside the gas tank. I believe 04 was the last year of the external fuel filters for Envoys and Trailblazers.

04 Trailblazer will not start. Replaced fuel pump, still no start. Powered fuel pump with hot wire, makes pressure still no start. Starter relay does not energized. Any sugestions?

Could be a bad starter/solenoid, but more than likely it is the ignition switch. These have been known to fail in various ways. Go to and do a search on "ignition switch", there should be some threads on how to replace the switch.

How do I change out the fuel filter on my 2005 Trailblazer (6-cyl)?

The fuel filter for your vehicle is located inside the fuel tank and is part of the fuel pump module. There isn't an external filter that you can change. I believe that the filter is sold only as part of the pump module so if it is indeed plugged you have to replace the entire pump module. I would have the fuel pressure tested to be sure you actually have a filter problem before replacing this as it is quite expensive.

Where is the fuel filter located on my 2004 Chevy Trail Blazer? WE

On 05+ Trail Blazer, the fuel filter is integral with the fuel pump inside of the fuel tank. It is a non-serviceable part. On 02-04s, the filter is on the drivers side frame rail at about the B-pillar. If your trail Blazer is a late 04 which means that it was build close to the 05 Trail Blazer, you may have a non serviceable fuel filter. Good luck and check under your Trail Blazer or look at your manufactured date sticker on the door which would help you indicate if your 04 is a early Trail Blazer and you'll have the fuel filter on the inside frame rail under the driver's door.
