Taurus fuel pump

I have some type of wiring problem it seems. My alarm system the blinks "theft" on the dash will blink. And at the same time the fuel pump will run in sequence. The key would be off too. It always kills my battery. Im wondeing if anyone has had the same problem and i they fixed it what pointers could you give me.

I really have no idea without hands-on diagnosis report from a qualified tech, but one thing that comes to mind given your symptoms is that the PCM is involved, as it has the capacity to energize the fuel pump and well as activate the security light. I wonder if when this is happening you can do a "jiggle test" on the PCM harness to see if that interrupts the fault.
