when turn off or on? Meaning when you turn key off it stays on or starter stays on when starting?

Fuel shut off solenoid

Also, if the engine has less than 100,000 miles, the solenoid and labor are covered under warranty.

It happened to me. That's why I know what it is.

Put a circuit testor on the hot wire going in to the fuel pump solenoid and see if the current stops when you turn off the key. If it does, and the engine still runs, you have a bad solenoid. If you still have current in the wire when you turn off the key, you may have a bad ignition switch.
