Art, you have my utmost respect on this most would have simply thrown in the towel. No one knows it all if they ever say they do you can call em a liar. Prolems such as what you're dealing with is what I do everday, however I find it more difficult to strategically diagnose it over the internet. I believe you have proven that you have a failed sensor, and I must apologize about comments made to disregard them all together, as most systems I work on only use them for starting purposes only.After googling your system and quickly reading some of it's operational characteristics I believe it requires a constant cam sync input. Good luck with this and let us know if the new sensor fixes your issue. Joe Oh almost forgot, I looked for your sensor part number2348 on MSD's website but could not find it with a number search, however if it's stated you can use between 8-14 volts then it wouldn't hurt to hook 12 volts to it I just don't think it will make any difference. By the way does your sensor have voltage when you crank it and when it's running cause I noticed the ECU is responsible for supply voltage? Just another thing to think about.
