Sounds like the fuel pump relay is sticking closed when powered off.. To verify, try 'taping' lightly on the relay case and it should go off.. Fairly common for this failure..

Should be close to the air box/left fender inner apron/hinge area.. Should be a weather cover over the relays.. 'Been a while', but I think there are 2.. EEC and fuel relays..
