I fixed it today, and I'm feeling a bit sheepish.IMG_20171021_203151.jpg
It was a fuse.
I have few excuses, except that I never questioned a fuse because I thought it wouldn't start or fire the injectors at all if there was a fuse issue.
I understand that the PCM connects the ground for the injectors to fire them. What is apparent now is that the start circuit and Acceleration Enrichment circuit are apparently parallel to the main injector circuit. Meaning that it can provide fuel for AE and starting without the main injector circuit being functional.
