Hello,

This vehicle has a fuel cut off valve, located on the top of the fuel tank. Next to the fuel pump access port.

And the fuel cut off relay is in the passenger compartment fuse box. Under the driver's side dash.


Here is a guide on how to test relays:

I have attached the diagrams showing the locations of both of those components.

Please let me know if you have any questions.
Thank you.
