01 disco 2. I had to replace the radiator core support and had to bleed the ac in order to get it off. Everything got put back together right, but when going to start the vehicle i ran into this problem. Ran fine prior to radiator core support replacement. I borrowed an obd reader from the auto parts store and it reads "No Powertrain DTC's or Freeze Frame Data is presently stored on computer" I cant get it to pull any codes. Any help would be appreciated! Thank you.
