I went to start my FD that hasn't been started in about a week this morning and had to really crank her (probably between 2-4 minutes total) with the gas pedal pushed to the floor the entire time before the engine caught. I honestly thought that the battery would die before engine caught, but it caught and slowly came to life (as it always does when it's cold). Did my fuel system de-pressurize over the last week? I only had a couple of gallons in the tank when I tried to turn the car over.

Thanks!
