Many thanks to jbowser for helping me to discover my error. I was looking at the fuel injector ECU, not knowing that the ignition ECU was directly behind and slightly above it on the firewall (not on the exterior wall).

I have 11.73 volts to pin 6, continuity to pin 20, but no continuity to ground on pin 14. Bentley 280.11.4 says to check the ground wires under the intake manifold.

I see one yellow wire in a plastic clip attaching midway back (coming out of a red wrap)and a couple of other wires that look like they are attached to sensors.

Would someone please be my knight on a shiny (or grungy) keyboard and let me know what I'm looking for? I don't want to break something else, especially if all I've been looking for all this time is a bad ground.

Thank you to all who've tried to help so far!
