Your 2005 Chevy trailblazer makes a weird sound when you first start it up for about 60 seconds I sounds like a motor or something building up pressure.?

yes and it's not all the time. I was told it is the fan assembly getting/mixing oil. It almost sounds like a jet engine, but quiets in a minute or two.

Is it necessary to depressurize fuel filter on 2004 Trailblazer before changing fuel filter?
Open the gas cap to depresurize. Have a container ready as you may get half a cup of fuel that comes out. www.trailvoy.com - All the answers for your trailblazer by true enthusiasts! I have to respectfully disagree. Removing the fuel cap will only depressurize the system if there are no in-line check valves in the pump, filter, or pressure regulator. Since the Trailblazer is a port injected vehicle, it maintains at least 40 psi in the lines while parked to allow for a fast startup. Pull the fuel pump relay and start the truck. After a few seconds the residual fuel pressure will be used up and the engine will stall. There will still be some pressure left, but far less than the 40-80 psi most vehicles run at.
