Did you say the vehicle doesn't seem to be getting fuel? Do you mean the fuel pump doesn't appear to be working?
The p1676 code indicates a problem with the security key system that keeps your vehicle from being started with an unauthorized key. If the chip in your key has died it could keep it from starting and trigger this code, but it would not make it misfire or stall while driving.
