Fuel Pump on Car Isn't
 

:( Has any one experianced their fuel pump running but the car is off?

I noticed today that my fuel pump was running. I got in the car sat down heard a wwwwwhhhhhuuurrrrrrrrr sound that didnt stop i realized that it was my fuel pump. I put in the key turned it on and it stopped. What would cause the pump to run will the key wasnt in it???

I have an aftermarket alarm (arrow 3)
