The following are mazda/ford Part numbers for the coil itself, as listed in the TSBs.
I have no idea what they will charge for one of the above, as a new disty costs in excess off 300 bucks. (Alternatively, you can get a second-hand one from a wrecking yard)
If your coil is fried, replacing the coil will fix your problem. However, the HEI mod with external coil remains a good idea, as any future failures can be repaired quickly and swiftly.
Do you have any malfunction codes? (a similtainious failure of both the crank and cam sensors can cause a no-start in the 93-94)
Have you checked the EGI-INJ fuse as suggested by Gehofff?
