Truck takes 2-3 tries to start when has been sitting for an hour
We have a 2006 F-150 5.4 liter Lariat that takes 2-3 starts to run when has been sitting for an hour. It's not the E-85 either. It seems like after we put gas in it, is when it doesn't want to start. After the truck has been sitting for over an hour, it seems like it will start right up, with just a bit of hesitation after the motor turns over. BUT, when there's not much gas in the tank, it seems to start easier, any advice?
