I have a 1999 sierra, just recently the fuel and temp gauge stopped working, abs light is on, in the messsage center it keeps flashing security, battery, and low fuel. I unhooked the battery thinking it would reset something, turned on the key and it fixed everything. Started the truck up and it ran fine for about 2 minutes then the problems all came back. Even with problems the truck runs and drives just fine.
