Electric Anomaly: 99 Siliverado 1500

[bigburban383]

Im driving this 99' Chevy short box 1500 w/ a 4.3 liter(I know, its gay) with a crazy electrical problem. The gas guage goes to empty, so it flashes low gas and the ABS lights on and it also flashes SECURITY. What the heck is going on?

Try disconecting BOTH battery cables and touching them together. Just PLEASE make sure they are BOTH disconnected from the battery when you do this. When you do that it resets all of the computers in the truck and clears all of the codes from the computers. If that doesnt fix it you need to get a code scanner and retrieve the codes from the vehicle.
