Question 1988 GT fuel pump issue

hello, im looking to find out what would cause my fuel pump to continue to run after the car has been turned off ? Ive had to disconnect the battery to get it to stop running? Any ideas would be greatly appreciated.

start at the eec relay, then move along the circuit to the pump

eec relay is by the ecm, pump relay is under the driver seat
