Delayed start 04 RX 8

Replaced the battery in my 2004 Mazda RX-8, seems to have a 7 second delay like it wants to start before it actually fires.. I've changed the coil, plugs, battery, checked the alternator, fuel pressure.. Coolant, everything is good. Would me upgrading my coil(s) do anything. Don't think it's the ignition switch or the fuel pump, both about 6 months old. I'm stuck
