I’m chasing a crank no start issue where the injectors are not firing. Have 2 ecu on hand, one with link and other unmodified. Looking for a member who would plug both my ecu into their car and see if their car would start. Portland/Vancouver/Longview area prefered but can drive further on my day off.
 
This log shows the engine cranking and cranking, and a few seconds of idle at 1.3k at 77 second mark. the black/yellow wire for start enrichment id not hooked up and hasn't been for the 9 years its been running prior to the latest engine rebuild.

Injectors do not fire, confirmed with a noid light and my fluke 87 multimeter at min/max setting shows high of 12v and a low of 8v while cranking. engine will run on starter fluid so there is spark. I'm thinking a bad injector driver circuit not giving a ground internal of the ECU, reason the ask for help. Wiring harness does not have tape on it at all thinking bad wiring.
