I have a 2009 ssturn outlook xe awd. I replaced the coils and plugs. Took it for a drive, everything ram and sounded good. The next morning after I left for work my wife went out to the car and heard what sounded like a fan running under the car near where the gas tank is. The only way to turn it off is to disconnect the battery. It still runs fine while driving, but the fuel pump keeps running. It also stops if you pull the fscm fuse. Ive had people tell me its the relay, but I cant find what relay it would ne. Any thoughts?
