    My daughters 2005 cobalt ran great for three years, sat for two months and will crank over but will not start. No fuel pressure and no spark, i removed the battery connections and cleaned, removed front head light and cleaned negative ground connection. When the key is on there is no power to the fuel pump fuse and the fuse is good. Also removed and cleaned the two positive cables under the hood that goes to the fuse and relay bus.

    If you put power to the fuel fuse you can hear the pump come on and no power to the Emissions, pcm/ecm, and injectors fuses with key on
