On a 1992 Lexus SC400, the fuel pump relay is located in the engine compartment's relay box, which is situated near the driver's side near the fender. To access it, you may need to remove the cover of the relay box. The relay itself is typically labeled, making it easier to identify among the other relays. Always consult your vehicle's service manual for specific details and diagrams.
You should not bypass the relay. Repair the problem.

The fuel pump on a Lexus GS 400 is located inside the fuel tank. To access it, you typically need to remove the rear seat and the access panel or, in some cases, drop the fuel tank. It's important to ensure the vehicle is properly supported and that safety precautions are taken when working with fuel systems.

In a 1992 Lexus SC 400, the fuel pump fuse is located in the fuse box under the dashboard on the driver's side. You will need to remove the cover to access the fuses. Look for the fuse labeled "Fuel Pump" or refer to the diagram on the inside of the fuse box cover for its exact location. Always ensure the vehicle is turned off before checking or replacing fuses.
The fuel pump is an integrated assembly (fuel pump+sending unit) located inside the gas tank. By the way, the 2000 Land Rover Discovery also has a fuel pump relay. This particular relay is a common problem in Land Rovers, and normally goes bad much sooner than the fuel pump. So in case you have not checked it out, it might be worth considering the fuel pump relay (which usually costs less than $20) before replacing the fuel pump assembly (labor-intensive, and expensive - usually around $400 for a brand new, OEM unit). The fuel pump relay is a small square-shaped part, yellow in color, with 4 terminals.
