It seems very coincidental that the ECM got fried when you had another problem...one of the causes of ECM failures is improper jump starting (like reversing the polarity of the cables). Is it possible after your battery was dead that someone improperly jumped it?

My initial diagnosis was also biased towards a problem with my fuel system because I had just replaced my shut-off valve and some fuel lines. After reading more about the schematics of the fuel system, I noticed that the "return" line was the line that had air in it. What was weird was that no fuel was pumping at all through the lines. What I did see was air bubbles slowly coming up through the return lines. My application of a vaccuum to the lines was also on the wrong fuel line. I had opened up my fuel prefilter and stuck the vaccuum hose into the well of the prefilter housing. I know, dumb. I should have hooked it up to the line that went into the prefilter instead to check flow.
It is probable. Unfortunately, I'm the guy that was jump starting the car so the only blame could be placed on me. I was using the charger on "low maintenance" and at the 50 amp setting for jumping purposes. I don't really know what reversing the polarity of the cables means. Can you explain?
Thank you for all your help guys. I really appreciate it. This weekend I'm going to attempt to replace my delivery valve seals based on Parrot Of Doom's DIY.
