I have a 2005 Ford expedition. with the 5.4 liter motor. just replaced motor with new one. Everything fit great, and went smooth. went to start and have N0 power from the ignition side of the starter, will click every so often but basically NO power. Very confused. Have double checked all connections, and changed starter. All lights come on, and do not dim when trying to crank. Is there a rest or a safety I haven't done? Please help if possible Brian
