My Fuel pump runs constantly now. Even after I shut the car off. I even unplugged the F/P Relay and it still ran. What is the problem?? It has been staying on longer and longer lately and now this. I unplugged all the relays under the hood and nothing. It only shuts off after disconnecting power. Help I can't just keep unplugging the battery.

Try the Oil pressure sender down by the oil filter. If that is stuck, it will keep the pump on.
