      Joe, thanks for your reply. The starter motor runs, engine turns fine. I don’t hear the fuel pump at all during startup, I was wondering if the Anti-theft device would disable the fuel pump, but schematics in the Hayne’s manual suggest not, as you have suggested. Though, I know ford has changed this car significantly in it’s history and I’ve found this manual not completely accurate. When it did run yesterday, the engine ran smoothly and had no apparent fuel delivery issues. I think this is an electrical issue.

      I don’t hear the fuel pump turning on when the key is in the “on” position though I do hear a series of clicks. Unfortunately, Ford designed the car so that the fuel pump relay is not a serviceable part, it must be replaced as a whole “control” module. It appears that there is not juice flowing to the fuel pump, I disconnected the Inertia switch and ran my multimeter across the harness, it only had a potential of 0.38 V…I’m going to try to apply +12 V to this circuit to see if I can get the fuel pump to run and go from there.
