This may be a dumb question but did you unplug the PCM to see if it was blown. I'v seen it happen.



I have disconnected all of the following load devices:
ATX solenoid plug
EVR solenoid plug
MAF plug
IMRC plug
A/C WOT relay
PCM plug under P/S reservoir <<<<<<<<<<<<<<<<<<!!!!!!!!!
EVAP canister plug
IAC plug




Pull the computer - the little box in the kick panel, unplug it - plug in the 20 amp fuse and see if it blows. If it does, the problem is from the battery to the pcm feed or one of the powered circuits. If it doesn't, the pcm is shorted internally. Lots of floating grounds under the hood of the tour to fool a meter. My wiring diagrams from Ford don't match my color coded harnesses, so make sure they are right.
I've rewired cars that had melted harnesses and found lots of incorrect diagrams.
