2012 nismo 370z won’t start after gascap change

[Datnismo3323]

So recently I’ve been having an issue with the “loose gas cap” message. Got tired of it and replaced the cap, got one from autozone to see if maybe that made it go away. Sure enough my temperamental little bag of horses decided not to start. So with some gas added I get her up and running keep in mind it now will not start without pressing the gas. No codes, old cap works fine car starts. New cap, car runs in limp mode and won’t go past 3500. I’m beyond how that can affect anything but I’m not very savvy about gas caps and what they can cause to go wrong. Any advice would be nice before I pay the luxurious 160 dollar diag fee. In my opinion is sounds like a faulty sensor, maybe crank shaft, mass air or canister purge valve?
