How do you remove the fuel shut off chip located in dashboard on a 1991 Camaro RS?

There's no standard "fuel shut-off chip" located in the dashboard of a 1991 Camaro RS as part of the factory equipment. Fuel shut-off systems in those vehicles are typically controlled electronically through the main engine control module (ECM) and not via a removable chip in the dash. A physical switch might be present, but it's not a "chip."

If you're referring to something someone has added aftermarket, you'll need more information. The location and removal method would depend entirely on the specific aftermarket system installed. It could be anything from a simple switch to a more complex device. To safely remove it, you need to:

1. Identify the device: Take a picture of it and try to find any markings or labels that might identify the manufacturer or model.

2. Locate the wiring: Carefully trace the wires leading to and from the device. Take pictures to document everything before disconnecting anything.

3. Disconnect the power: Before disconnecting any wires, always disconnect the negative (-) terminal of your battery to prevent electrical shorts.

4. Consult the instructions: If there are any instructions or documentation that came with the device, refer to them for removal instructions.

5. If you have no information: If you cannot identify the device and there's no documentation, seeking help from a qualified automotive technician is the safest approach. Improperly removing an aftermarket fuel shut-off system could lead to vehicle damage or even a fire.

In summary: What you're describing isn't a factory feature. You need to identify the aftermarket device to determine how to safely remove it. If you're unsure, get professional help.
