[MustangGT1990]

The other day I started my Mustang and when I turned the motor off my fuel pump was still running. I started it back up and cut it off again. It was still running. I got out and disconnected my negative battery cable. I tapped on the fuel pump relay a few times then reconnected my battery cable and started it again. It seemed to be alright for a little while then it did it again. I bought a new fuel pump relay and put it in. It did the exact same thing. Now it has gotten worse, it will NOT stop running. What could be causing the problem? Is it my ignition switch?

Just to sum it up for you, with my keys in my pocket the fuel pump runs non-stop if the battery is hooked up.


Thanks for any help!
