I have had a few Fords over the years have issues with the park override switch (or something called like it) that keeps the vehicle in park unless the brake is pressed. Needed to put it into neutral then start because it did not require the brake to be pressed to start then shift into drive. I still pressed the brake but the vehicle's would at least get me going.
