Started with the P0455 code and smelling gas fumes at rear of Envoy. Husband got under it to look for gas leaks and gas all around the inlet check valve connection that fuel filler hose hooks to at rear of gas tank. Check online about this and it appears to be a big problem for a lot of 2003-2004 GM vehicles but the refuse to make it a recall. Beware if you are buying or own GM vehicles in these years.
