Congrats on your first Skyline!

In regards to your starting issue I'd maybe check out your IACV/AAC valve and fuel pressure regulator. What is the idle like when you start it up?

I'd clean the IACV unit- when you press the gas you allow more air into the throttle body. If your IACV is clogged or not functioning properly it might not have enough air to start up. Fuel pressure reg could also be clogged. Do you hear your fuel pump priming?
