I've just changed the fuel pump on the 97 Cadillac Deville Northstar last week and now the electronic gas level indicator is moving up and down between empty and a 17 gallons. There is no engine light or other sensor on but this very annoying, when I know the tank is full since just filled. Does anyone have an idea of what's causing this? Please advise and thank you.
