I would personally load the file in Excel and write a quick macro to add quotes to all cells, before re-saving as CSV and doing the import with delimiters... untested macro example:
VB Code:
  1. Dim CurrCell as Range
  2.   For Each CurrCell In ThisWorkBook.WorkSheets("[u]Sheet1[/u]").UsedRange
  3.     CurrCell.Text = """" & CurrCell.Text & """"
  4.   Next CurrCell
