Ha! I did the same thing, but I froze my fan in a block of ice after
a bit of snow rallying!
Yes there is a fusible link, that was later replaced with a maxi-fuse
in the under-hood fuse block. I believe the fusible link is supposed
to be in a similar position, but mine had been changed out to the fuse
(93).
You will probably need to replace the IRCM as you fried the traces on
the board. I cheated and soldered in som wire to jump the burned
traces and repaired my IRCM. It was a temporary fix that has now been
in place for about 4 years.
Look in the service manuals for the exact location, but yes, there is
a fusible link/fuse, and yes you proably blew it.
Good deducting, no fuel pump-blown ircm.
