Hi All, Just picked up a 2003 G35 sedan for my daughter to take to school. Here's the issue. It cranks over very strong, but it takes longer than it should to start. Runs strong once it starts.

It has 115k miles, auto trans, K&N cold air intake.

I was thinking spark plugs so i bought a set of NGK Iridium based on forum posts, and will install after work today. If not that, is the fuel pump next? Could it be computer related?

Thanks for reading.
