Anyone else having hard start issues on initial morning start?My car takes 3 to 4 cranks before it starts. Once the car is warmed up i hit the start button and bam 1 crank and she fires up. My 2009 Vette never did this. Any replies welcomed

Normal; it has to do with direct injection, the fuel pump needs prime the system to reach appropriate fuel pressure. Direct injection runs much higher base fuel pressure than a standard fuel injection system (2XXX PSI vs. 40ish PSI).
