Best thing to do is test fuel pressure with a gauge at the fuel rail Schrader valve. Also sounds like your sending unit in the tank (on the fuel pump) is not working. Fuel pressure should be 58-62 psi and hold with engine off. These 4.3 engines have issues with spider fuel systems it could be this.

Sounds like the fuel pump module in the gas tank is not getting power. When the gas gauge swings past full the sending unit, which is part of the fuel pump module, has lost power. This can prevent the fuel pump from running. HTH. -Jim

So I can assume the tank needs to come out and go from there?
