Yeah no kidding. Slap some dielectric grease in there to prevent future oxidation and to promote a good connection. There was a bulletin to slap grease in the ecu connector on these cars.
Like I said in your other thread, these mid 80s 740s have the biodegradable wiring. It may have shot wiring under the intake or at the firewall.
Have you checked continuity between the injector ground wire terminal and the ecu!? Do so and wiggle test the engine wiring harness and see if the resistance goes open or high.
One MORE test....use a test light between injector ground and a known good ground. Make sure is does NOT light up=short to voltage. Do it with key on.
