What for a starter?? I've never bought one funny enough being prone as they are, but as u look down the front of the engine there its right there, u will see the THICK red starter cable running to it. Personally i'd buy a New Ford one and not a re-con, or u might get lucky and get a god second hand one cheap.

Before he spends out though get him to have a battery check done, which is usually free. This will also cause the same problem if the battery is getting weak.
