Chevy doesn't use a "cutoff" or interia switch like Ford does. Chevy activates the fuel pump through a relay controlled by the PCM. As a backup, the oil pressure switch is involved in the circuit, so that if there is oil pressure, the fuel pump gets power even if the relay fails. If the vehicle is not starting, and your fuel pump is not running, you may have a melted connector at the top of the fuel pump/sending unit assembly. You can get a new pigtail wiring assembly from the dealer, and the top of the sending unit assembly will also be damaged, so you will need a new one of those as well.
