Excessive crank times can be low compression, or more commonly the fuel pump is losing pressure when off and draining back to the tank slightly. My 2.5 does about 1.5-2 seconds every time, maybe up to 2.5 seconds in the winter on a cold day. Another common thing for computer controlled cars is that the computer has to wait for the engine to make enough of a revolution to get the cam and crank sensor locations. Older carbed cars with regular distributors could pretty much fire as soon as the key was hit if the gas was pumped a couple times as it did not need to wait for those sensors to pick up location.
