Always check body grounds. You may have good power to the engine with a good ground still, but your body grounds control power to all else.

what is the problem with the speedometer.

I leased one of these, great truck. Some Fram fuel filters were recalled and the filters would leak at their connections. You could have a stuck fuel injector if your problem is mainly after parking it overnight or for long time periods. There are some fuel vapor lines for the evaporative recovery system, but usually even a small leak will set a code. Can't remember if the Lincoln truck version had a cabin air filter but if it does, the filter box may not be seated tight.
