OBD Port Not Working.
I have a 2005 that's been cammed and full bolt ons. Got a decent tune on it before the cable shorted out. Went back to finish everything a few weeks later and HP tuners will not connect to it. Neither will a normal code reader. Anybody else have this issue or a solution?

Same thing happened on my Silverado, and it turned out that the cigarette lighter fuse was the same one powering the OBD port. I had popped the cig lighter fuse on accident, thus resulting in a failure-to-read OBD when I went for an inspection. I located and changed the fuse, all is well. Maybe start there...

Haven't heard that one yet I'll definitely have to check it. I was leaning towards bcm or ecm. But couldn't imagine the car running and driving without issues if one of them were bad especially the ecm.
