It's your fuel pump I had this same issue with my 07 then I replaced my fuel pump and no more delayed starts..I have a 2006 Maxima, when it's cold it start slowly. When the vehicle warms up it starts up immediately.
I replaced the cam and crank sensors. Also, the oxygen sensors had been replaced.
I don't have any fault codes.
Please help, I'm at a lost and ran out of directions.
Thanks
