Come to think of it, I do not remember hearing the fuel pump humming when I attempted starting. No clear signs of corrosion and no burns at the fuel pump connector, but jiggling it worked and got me home. There were no signs of corrosion either on the dreaded factory test plug when that left me stranded, so I'm still thinking that this is the issue at the fuel pump connector. I hoped someone else had experienced and recognized the same problem. I will go through every connector and ground as OMG has suggested.
I appreciate the suggestions, advice, and shared experience- I need to regain trust and confidence in my bird.
