No power at diagnostic port

I dont have power at my diagnostic port under my dash in my 01 7.3L. I went to program it with a Hypertech chip and nothing happens. I tried it in another truck of ours and it worked for that one so I know its a problem with my truck. Any ideas?

I don't have a 7.3 so I don't know if the fuse locations are the same but here is a good link.

I found a manual for an 01 in one of our other trucks and the one that It says that It should be is still good. It was number 3 fuse. Now im stuck. I guess I will trace wires under the dash or something.

If the cig lighter is tied into that fuse and the fuse is good check the cig lighter for power also

It is the cig lighter fuse, when you replace it you will have power. Thanks for purchasing our product
