No worries, and often its not the fuel pump fuse the problem, but the fuel pump relay and it pathways/relay clip points in the fuse box the problem isntead.

So the easy way to test the fuel pump pressure and wiring, is to just jump it out at the fuel pump relay point to start with. This bypasses the relay and ECM command to energize the relay to start with.

Also comes in handy if you need to drain the tanks through the fuel rail schrader valve on the driver front side under the fuel rail cover as well.
