First, do your brake lights work? Ford has a "BOO" switch that won't signal the EEC unless the lights are good. The bulbs are acually the ground path for the circuit. "BOO" stands for Brake On/Off. Can't remember if you're car has this or not.

The site will be back up early this week. It is down for maintenance right now.
The absolute, very first thing to do when troubleshooting these cars is to read any codes stored in the EEC-IV.
Check to make sure your SES light will come on. When you first turn the key, all the dash lights illuminate - and the SES light should work as well. If this is ok, all you'll need is a short jumper wire, and you'll be reading codes. More on this later.
Keep us posted.
