What I normally do when someone brings me a Ford with a CD stuck in the OEM stereo is to unplug the power connector going to the stereo over night. Plug it back in the next day and it'll usually spit out the CD. Occasionally you have to do it twice.
It's a fairly common problem with CD players. Something in the mechanism just needs to be reset, and for whatever reason, if you leave the stereo unplugged for 8+ hours, they'll do a complete CPU & mechanical recycle upon power up.
If something in the mechanism is broken, you're S.O.L.
