2006 Cadillac DTS Question: the fuel gauge is not working?

Please do not ground any wire for your fuel gauge, you can fry a computer, this is not a 1972 Cadillac, the system is networked and much more complex. You need to scan the data stream for the fuel gauge, to see if it is the gauge, the network, the Fuel Level Sensor etc. Many GM cars have harness problems with their fuel gauge and level sensors.
