When the car is off there is a buzzing noise coming from underneath. Kinda by the fuel pump. It doesn't shut off unless the battery is unhooked. We don't want the battery to drain. Please help.

Hello,

This sounds like you have a short to power somewhere in your vehicle's fuel pump circuit. In the diagrams down below I have included a wiring diagram for your fuel pump circuit and a guide for how to find shorts to power in an automotive electrical circuit. You will need to use a digital multi-meter to do this, so here is a link describing how to do this, if needed:

Please go through these guides and get back to us with what you find out.

Thanks,
Alex
