96 gt-keeps blowing the fuse for the EEC

My 96 gt was parked for over a year and ran great when I left it. When I came back and started it up, it began blowing the 20 amp fuse for the EEC and I have also noticed the cooling fan comes on sporadically even when the engine hasnt been ran but maybe 30 secs. Is this a problem with my ccrmor what? I have put a obd 2 code reader on it but it wasnt turning the check engine light on and threw no codes. Help! At my wits end.

Honestly this COULD be a bunch of things. Start first with a through visual inspection. Pay special attention to the O2 sensor pig tails. Look for evidence of water or rodent activity.

If the PCM fuse is blown, then the ODB2 scanner won't be able to talk to the PCM. It's dead Jim...

Also the cooling fan circuit is a fail safe circuit. IE, it takes a signal from the PCM to make the cooling fan NOT run. So if the PCM is dead, the default action is to run the cooling fan. This symptom isn't necessaryly a problem but a sign of no power to the PCM.
