Coded pumps have to be re-programmed to the vehicle or Virginised or
it will not start, (imobilised)
idont think the JTD pumps, are coded, not sure about the later ones,
but id presume they wouid still be on the Bosch mechanical set up
you wouid be able to tell off the pump,if its got a Module box on it all Armoured up it will be coded,
