Skip over the GM scanner diagnosis part.
Here's the best I can find. Alldata really helps in some case but when it comes to systems schematics, GM sux
What you can do.. On top the crossmemebr over the rear diff, is a major ground point. unbolt them and clean terminals. You may want to relocate the grounding bolt to face rear so you can see it.
find the harness leading to the sender assy at rear of tank. Wiggle to see if gauge starts working.
Good chance pump had been replaced. When that happens defective OEM pump connector is as well. Supplier includes butt splices which SUCK unless you have pro level tools to install them.
