Westend, where is the fuse/breaker you were talking about?
Look towards the firewall, the box is usually bracketed on a fender or some other metal in the engine compartment. It may have a plastic cover. This is just for some GM vehicles, it may not be yours. An owner's manual should depict any and all fuse and breaker locations.
Another trait of certain GM vehicles is a failure of the theft deterrent module. When key is turned to the "Run" position a small voltage is sent to a Body Control Module. That module, in turn, sends voltage to the ECU and various relays like the starter and fuel pump relay. If the BCM detects a different voltage because the vehicle has been tampered with, the engine won't start or the fuel system will be nonoperational. Oh, for the good old days when a guy could diagnose a starter problem with an old screwdriver.
