On my 1g my fuel pump comes on and stays on whenever the key is turned to on with the engine off. Not sure what would cause that unless the mpi relay is faulty. Any ideas?

Ummmmm... My pump primes (turns on) when my key is in the on position just before starting. As stated, it "primes" the system up to operating pressure, because when your car shuts off the pressure from the fuel system slowly drops off back in to the tank (hence the fuel return line)
Sounds pretty normal, maybe you just never noticed or the pump got louder because its going out?
And once the pump is on, its on, it will just sit and whine... it doesnt shut off then start, then shut off and start while the car is running or in "on". It is constantly on once you turn the key to on or start it
Apparently in ecmlink the activate fuel pump was checked.
