  this water pump is driven by the timing belt. you must be
  extremely careful that none of the cam gears move and all
  timing marks are observed when reinstalling the timing belt. better remove everything and recheck your work.

  if all marks lineup; cams and crank. then check your cam and crank position sensors.... code 12 and 13 on OBD I diagnostics
