Why does my fuel gauge stick on empty and low fuel idicator appears and will not allow my car to start but i kniw i have a half of tank of gas

Hello, if you're absolutely certain there is fuel in the tank, it would seem to me that there's a power issue at the fuel pump and sending unit in the tank, or a concern with the pump and sending unit itself. Hands on testing is needed to find out what's going on, but that is definitely where to look. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
