Question about 2000 Chevrolet Silverado 1500
Message states service 4wd is there a problem or is it a pre set message in the computer to check or change fluids. the front end feels great! also when i fill up my tank with gas, the gage go to empty and the message center states low fuel then the gage goes back to full the the message gos off.
Not sure about the fuel gauge, but I am willing to bet you need a new 4wd switch. This is pretty common on these trucks.
The fuel thing might be a bad cluster. This is also a common problem on the gm vehicles. I have 2 silverados, an impala and a malibu and they all have had funky problems with the clusters.

Tips for a great answer:
Transfer Case Description and Operation for the Transfer Case - NVG 246-NP8
Transfer Case Description and Operation for the Transfer Case - NVG 261-NP2
Transfer Case Description and Operation for the Transfer Case - NVG 263-NP1
The SERVICE 4WD indicator is located in the instrument panel cluster (IPC), and shares the common power and ground of the IPC. The transfer case shift control module controls the service indicator by sending the IPC a Class 2 message. This indicator may be controlled with the scan tool using the IPC device controls.
You should take it to the dealer an have it checked for DTC'S -diagnostic trouble codes
