It may have not damaged anything since it did start; but your Cap idea sounds interesting!EDIT:
and from memory, if the engine was off @ that time and ign sw is off, then that 9v just travelled back to the load side of the FP relay; since the FP relay was not "closed"? But as you wrote; that ckt also routes via a splice & then thru the inertia switch to the EEC?
Burnt PCM pic in a 94; "...the capacitors inside burned and leaked on the board. it happened to all of them, one was worse then the others..." see Mike's pic here; http://img.photobuck...0069/ECM002.jpg
Can you check for Codes; such as this way by our pal BroncoJoe?
SELF TEST - COMPREHENSIVE & Connector Location pics, Bronco & Ford; "...The self-test plugs were mounted on the passenger side fender on 1985-86 EFI trucks; The self-test plugs are located along the driver's side fender behind the air filter box on 87-95 EFI trucks..."; miesk5 NOTE; Self-Test Output (STO) is the Pin in the Lt gray Connector and Signal Return Ground (SIGRET) is Pin E in black Connector in 87-95; The engine temperature must be greater than 50°F (10°C) to pass the KOEO Self-Test and greater than 180°F (82°C) to pass the KOER Self-Test. Run it around to heat the engine up and shift thru all gears incl Reverse. Then turn off all accesories/lights, etc. Make sure A/C is off and transmission is in Park (automatic) or in Neutral for a Manual & release clutch. Do Key On Engine Off (KOEO) portion first. Look Codes up in my broncolinks.com site using the new Search function.
