SOURCE: FUEL PUMP FOR CHEVY SILVERADO
fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

First of all you need to get this problem fixed ASAP. While the airbag light is illuminated, your SDM (Sensing and Diagnostic Module aka: the brain of your airbag system) shuts of power to the airbags. In which, if you are in an accident your airbags will not deploy while this light is illuminated. You need to take your vehicle to a GM dealership. A Tech 2 scantool is needed to retrieve the code from the SDM. Hopefully it won't be a costly repair, but is something that defineatly needs to be corrected soon. Good luck and hope all works well.

Had the same thing happen to my truck, the blen door actuator is under the console on passenger side, but the heater core is going to be clogged if you dont have any heat coming through, but a/c works..

Common problem on the 03-06 Silverado instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out.
