How do you fix the p1093 code on your 2004 duramax?

The P1093 code on a 2004 Duramax typically indicates an issue with the fuel rail pressure sensor or the fuel system. To fix it, start by checking the fuel rail pressure sensor for proper operation and connections. Inspect the fuel filter for clogs and replace it if necessary. If those components are functioning correctly, consider examining the fuel lines and injectors for any leaks or blockages.
