I have been having a no start issue with my LBZ. I finally got it to start and had check engine light on so I tried to hook up an OBD 2 to check codes and I have no power to the Data Link Connector. I have checked every fuse at least twice. I have changed braekers and nothing. What would cause no power to the Data Link Connector and what can I do to cure this so I can read my codes. All help would be greatly appreciated.

did you check the fuse for the cigarette lighter it is the one that powers the data link

I checked that fuse and it was blown but I thought it was just for the cig lighter nothing else. I will replace it and see what I get. Thanks for the info.

I replaced the fuse and it took care of the problem. I read the codes and got what I needed. Thanks again.
