whenever i shut off the stang, the fuel pump stays on for a couple secs longer and eventually it will shut down and this is when the key is turned all the way off b/c normally the car would just shut off, but in my case the fuel pump doesnt right away, any1 know what the problem can be? possible wiring problem? bad fuel pump? b/c occasionally it wont do it, sometimes it will shut off normally, its kinda concerning me

 

Could be a bad relay.

 

ok, so what does that mean, what do i need to do to fix it?
