Fuel pump

[Rangerman87]

The fuel pump in my truck continuesly runs,I've replaced the the fuel pump relay,fuel pump,ignition switch,etc.What would cause it to constantly run and it's pretty loud,I can hear it while I'm driving.Any help would be greatly appreciated,thanks.

the pump is supposed to run the entire time the truck is running, If it doesn't then you have a problem.
