i ended up sending the ecm and prom back to the guy i bought it and the modified harness from back in march. I Was surprised how helpful he was when i finally got in contact with him about it, he said to send it and he'll check it out. I was expecting him to say it wasnt his problem or that there'd be an extra charge, but all was good. A few days later he emailed me that he got it and tested it. He found there was a corrupted file that was causing the issue. He told me the SES light should flash or "wink" when the ecm is first powered up and it didnt do it, so he knew there was something going on. He said fixed it and made sure it was all ok. I'm very happy that ebayer seller stands behind his products. I just got it back today, so now tomorrow i'll try it out and see how it is this time, hopefully all is well.
