QUESTION: I have no lights at all.  Even the dashlights won't come on.  I tried to see if it was the anti theft system.  I unlocked and locked the driver side door and it dinged when I put the key in the ignition but went right back out when I turned the key.  The engine size is unknown by me.  It has eight plugs and four in the back are covered and have a computer looking thing on them.  I think it is 4.9
