If the starter isn't dragging, then i wouldn't say it would be the starter. It might be something to do with your fuel injection setup. Might be the throttle positioning sensor or a couple other items that generally cause a hard start. Question: Does this only occur when the engine is cold, or consistently no matter what engine temp? That should let you know whether or not its something to do with the engine/fuel inj setup.

There is a condition that causes the problem you describe---Try this to see if it starts easier---turn the key on and let the fuel pump run, but don't start the engine--do this a few times as the pump times out--see if it starts any easier. I had this problem and it is caused by a faulty check valve in the electric fuel pump or pumps or bad pressure regulator, that lets the residual fuel pressure in the fuel system bleed off, so when you go to start it there is no pressure in the fuel system and it won't start until the pressure builds up while cranking. There was a Ford recall on this, but it has expired. The fix is to change the fuel pressure regulator first and see if this fixes it. If not, there was a kit that installed a check valve in the return line at the offending fuel pump or the pump was replaced. If you have two tanks and one return check valve is bad, all the return gas will go to the bad tank, regardless of which tank is selected. I found a kit and repaired my two pumps by adding a check valve to both return lines , solved the long crank problem and the fuel transfer problem.
