You can get away with just releasing the fuel tank strap on the drivers side and letting it sag down. You can release the strap with a screwdriver. I had an 01 LS with that code. I replaced pretty much everything you're doing and nothing fixed it. A buddy of mine was able to bring home a GM Tech 2 for me, and it ended up being the fuel pump! The car had no issues starting or drivability issues... I would've never guessed.

theres a video I'm going to try to find right now.
