2001 Kia Sephia fuel pump issue

The fuel pump in my 2001 Kia Sephia won't shut off, even after I turn off the car. The only way to get the pump to shut off is to remove the 10a fuse in the fuse box. If I then replace the fuse (with the car turned off) the fuel pump starts up. If I remove the fuse a second time and put it back in, the fuel pump will stay off until I start the car. The car drives fine, I just can't figure out why the fuel pump stays on when I turn off the car. Anyone with insight here???

Sounds like the fuel pump relay may be stuck closed or fried. See if there is a relay labeled "fuel pump" in one of the fuse panels. Pretty odd that it would still run with the key off, though, since that should remove power regardless.

I think the relay always has 12v constant.

Thanks, Mark; then a sticky relay could be it.

What Hot says makes sense because a relay in other components works that way.

Take an A/C system's outside condensor unit. When you turn the key(thermostat), that sends power to the relay(contactor), which allows full power to come from out of car fuse (circuit breakers). And without the power directly having to come from the keyed ignition(thermostat).
