I have seen a few P0300 that were a result of a weak fuel pump. On older cars, this was easy... However since Nissan/Infiniti moved to a return-less fuel system it requires a special tool. You can pay someone to do this, or buy a "fuel tap" and 60 or 100 PSI gauge. This is the one I use: https://cj-motorsports.com/products/fuel-tap-npt-2-bolt. What ever you decide to do, the fuel pressure should be 50-51 psi at idle. Tractionless likes this.
