Yes, you'd hear no sound if the starter was completely dead or had totally siezed.

You my friend may have a PATS problem. Look at that little red light next to where your clock is, or if you don't have a clock, next to where it says "Contour" on the dash. It should light up continuously for a couple of seconds when you turn the key to "ON" Then it should go out. If it doesn't light up continuously, but instead randomly flashes or doesn't come on at all, you have a PATS malfunction. You won't be able to fix that yourself, you'll have to take it to a Ford dealer, not even a local shop will be able to fix it.
