My fuel pump is not working either. I’d like to rule all else out before spending $600.

Gas gage not reading right

Chevrolet Silverado 1500 2006 Lt, 6.0, 4x4, Vortex Max 199980 miles
After the dealership replaced the sending unit in the truck the gas gage started reading full or empty nothing in between and sometimes it will throw a check engine code. Would the be in the fuel pump or would that be a problem with the computer I’m really looking for a place to start. Is there a place that i could run a meter to see what the problem is before i start tarring into things?
