370z warm start problem

I had the same issue you are talking about. I would purchase a fuel pressure gauge from cjm or z1 to see what your fuel pressure is doing. After checking all the above statements, you or a dealership will have to dive into the horrible fuel tank to check lines or filter strainer. Does the fuel pump whine? Could be a bad check valve, fuel pressure regulator, but with your car being A 14' I don't think those parts could go bad so soon, but then again it could.

I had this problem although I was boosted and Uprev tuned and it turned out to be the fuel "trims" needed an adjustment.
