Before diving into the fuel pump replacement, make certain to safely relieve the fuel system pressure to prevent fuel spray and potential injury.

Start by locating the fuel pump relay or fuse in your vehicle’s fuse box. Remove it to disable the fuel pump, then try starting the engine; it should stall quickly, indicating pressure has dropped.

Next, disconnect the fuel line at the engine or fuel rail using a fuel line disconnect tool or wrench—have a rag ready to catch any residual fuel. You can also depress the Schrader valve, if your vehicle has one, to release pressure.
