The fuel pump may be bad but I suspect you are in for a complete fuel system cleaning. Gas goes bad and gums up everything!

Have you checked to see if your fuel.pump relay is working ? It.may be a blown fuse , Or it could be just a seized pump . Worst thing you can do to any car is let.it sit .Good luck
