How do you replace a fuel pressure sensor in a 2004 impala?

To replace the fuel pressure sensor in a 2004 Chevrolet Impala, first, relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Next, disconnect the battery and locate the fuel pressure sensor, which is typically found on the fuel rail. Unscrew the old sensor using a wrench, then install the new sensor by threading it in place and reconnecting any electrical connectors. Finally, reconnect the battery, replace the fuel pump fuse, and check for leaks before starting the engine.
