I will do that to see if the timing is 'normal' in limp home. From what I
read, it is just a few degrees advanced from the module itself. Then I know
the problem really does exist...

Good news! My manual shows the pinout for sensor ground D10 as being :
"Power Ground ?" It actually had the ? mark. Key on, engine off says it
should be 0 volts. I am getting a feedback on that line though. It ties into
the MAF, Coolant sensor, MAT sensor...those show OK on the scan tool, but it
might be a live ground. Exciting! Thanks again, -Matt-
