sounds like the relay is stuck, pull the relay out and check the connections for corrosion

I agree, pull the fuel pump relay and see if the pump goes off

check your starter soloenoid. The previous owner of my jeep hardwired the ignition. they had a few of the starter solenoid wires in random spots so when the key was turned on it would constantly prime!
