When i try starting the car in the morning or after a few hours of it standing it will not start. I need to swing the ignition at least a few times before she actually take and when it take there is a bit of a rough idle as if there is excessive fuel that needs to burn out before getting to idle normal. i have changed the valve under the intake manifold, 2 coils as well as the fuel pump. Please help

Has the check engine light come on? Have you checked the fuel pressure to make sure the regulator is working properly? Is there any smoke from the exhaust when it does start?

Engine light has not come on. We have check the fuel regulator and when it does start there is no smoke but a strong smell of unburned fuel.
