Hi Steve it was a new injector for number 6 and this has been recoded I have just done a noid test and have no power to injector 2 or 3 so will have to check for the offending connector/ wire or Fuse/ relay Can't find the relays except for one in the boot Quote Link to comment Share on other sites More sharing options...
