Please use punctuation - it's free. And it makes reading easier.

Reset the inertia switch. It's inside the R kick panel under the dash. The owner's manual explains more. If you don't have one, download the '95 or '96 version free from Ford.



If that doesn't help, get a Haynes manual & a cheap digital multimeter, and perform the ignition diagnostic procedure, usually in Ch.5 Sec.5 on p.5-5 (depending on which edition you get).

 

The cap is not turned 180 degrees is it? When you checked the spark was it a strong blue arc or a weak orange. If it is orange the coil may be weak.
