Is there a fuel pump safety switch on 2002 impala?

No, the 2002 Chevrolet Impala does not have a dedicated fuel pump safety switch in the same way some older vehicles did with a physical switch that could be manually turned on/off. The fuel pump is controlled electronically and is part of the overall vehicle's safety system. The system disables the fuel pump under certain conditions, such as a crash or other critical failure. These safety mechanisms are integrated into the computer system and aren't accessible through a separate switch.
