Default Fuel Pump stuck on -->

I woke up this fine halloween morning to find a dead battery on my '90 vert.

After getting it started, I found the fuel pump continued to run after the key was turned off. (in excess of 10 minutes)


Anyone run into this before, and if so what was the solution?


I'm running a totally stock 1990 GT convertible 5.0/5 speed.


Thanks!

I went through the same thing about a month ago with the relay sticking on.
