does it crank over or you turn key and nothing. check your grounds. chassis to motor. battery to chassis. even though its a 'new' battery does it have any voltage.

YOU HAVE 2 GROUNDS ON THE BATTERY FOR GROUND . SOME TIME S ONE GROUND IS FORGOTTEN, ONLY THE DASH WILL LIGHT UP. LOOK FOR A SECOND GROUND UNDER THE BATTERY TRAY.
