i stopped at store to get soda, turned key, truck won't start. it was like no power going to starter. nothing i tried worked. returned to stock, started. about a half mile from home, decided to drive home, no problems. downloaded tune, started, thought it must have been some sort of glitz. i didn't think much about till 3 or 4 days later, it did it again. same thing, i returned to stock, it started, turned it off, downloaded tune, it started. 3 or 4 days later, same thing. afraid i've somehow fried something , called H&S, told the tech the problem. he told me to check the adapter to the obdII. i sungged it up, put a plastic tie around it to make sure it didn't happen again. 3 weeks later, no problems.
