What engine do you have in your 2003? sounds like you may not be getting fuel to the rails. You will need a pressure gauge to determine if you are getting fuel ut there, or push on the test port and see if gas sprays out at you, don't get it in your eyes lol.
No pressure will be on the fuel rails unless the pump is running. Dont expect the system to stay pressurized with the engine off. That would be dangerous. If you flip the key to the ON position, do you hear the pump turn on and run for a few seconds before the ASD (Auto Shutdown) relay kicks it off?
thanks prblem fixed , added gas !! sending unit was stuck . Sometimes its the simplest things . The truck has gained a noticable 1mpg better gas mileage with the new bank 1 O2 sensor installed !
