well i found my fuel leak smell from a little slit in one of the lines. But now that thats takin care of, my car always cranks for a while before starting and it has a brand new optima battery. The only time it doesnt is if you shut the car off and restart it in within about 5min then she fires right up. Do you think its time for new injectors maybe? its got 127k? let me know. thanks

 

Have you checked the fuel pressure at shutdown, to see how quickly the fuel pressure bleeds off? Rapid bleed down will cause extended cranking?
