Are your jumper cables suitable for the task? Most cables that are available today are barely up to the task for a small car.
If they are, and still no response, then starter/solenoid would be the first place I'd look. Possible broken wire in windings/open short somewhere
I plead ignorance about the Ford configuration.
Could be a bad battery, perhaps a dead cell.
Possible, (but not likely if jump start is ineffective), failed alternator, leading to severe battery discharge.
Possible battery cable damaged, or bad connection @ starter/solenoid/relay. (Ford ignorance again)
Electrical difficulties can be a pain in the ass.
Good luck.
EDIT - you guys type faster than I do.
