I just took my truck in for a state inspection and they told me that my OBD is not working and they cannot connect to it. I flashed the truck yesterday back to stock and drove almost 300 miles since doing so. I am running Troyer tunes from an Xcal 3.
How can I flash the truck and read codes, but they cannot even get the OBD to connect? This really frustrating. Thanks for any help you can give me.

PS - I am still getting the obligatory P1000 code if that makes any difference.
Go somewhere else. They may have a bad cable. If you can pull codes and flash the truck your port is working. Usually the cigarette lighter fuse blows and you can't do anything. P1000 is normal after flashing or disconnecting battery. It just means you haven't completed the obligatory OBD drive cycles yet.

They might have rejected it because the P1000 code is making them think the OBD is not working, it is just a code which tells you that the computer doesn't have enough information yet to make a diagnosis.
I would complete enough drive cycles until the P1000 has cleared itself (not sure how long that is but you can check with your reader) and then try for inspection sticker again.

You MAY want to check your cigar lighter fuse. Unless I'm not remembering correctly, this fuse supplies power to the OBDII port, as well as the cigar lighter.
And, DO NOT flash the PCM back to stock - that just about guarantees an emissions check failure.
Edit: I just read your post more carefully, Norm! Sorry for duplicating you. Perhaps the fuse failed after the truck was returned to stock.

Agreed!
The p1000 code is a red flag for those testers.

Hope this isn't threadjacking, but can you elaborate on why you shouldn't flash back to stock? If I were going in for an inspection next week, should I leave it on Level 1, and just unplug the tuner?

Not a threadjack at all. The answer is YES! Simply unplug the programmer. (I'd remove it AND the cord so that the inspectors don't have anything to raise their eyebrows over).
Everyone (that I've read about) on these forums that has LEFT the tune in place for an emissions inspection has passed! Those that have returned the tune to "stock" have generally "failed".
Returning the tune to stock sets a "drive cycle" code that MAY take a while to clear. (There IS a procedure to clear the code faster, but you do not want to have to deal with it)! If this code is set, you will fail the emissions test - simply because the test "sees" any code as "bad".
So, in answer to your question, unplug and remove the programmer and the cord and leave the PCM programmed to Level 1.
That ciggarete lighter fuse did that to me when I went for my inspecdtion after I bought my truck in February. He knw right away what it was... changed it for free
