Alright guys, so i have a 2001 prelude manual. It was converted to the obd1 system withe the obd1 harness. Now issue I have is I'm not getting fuel prime or injector pulse. I checked main relay its good, hot jumped pump it's good (not to worried I can hot wire it to run) however the injector pulse I'm at a loss. I have 12volts going into each yellow and black wire on one side of each plug but I'm not getting the ground from ecm. When plugs are plugged in. I can go to the ecm and probe the wires for the injectors an they follow with 12volts so I know there is no breaks there... what signals or trails the command for ground from there?

Any help is appreciated.

I didn't check the crank sensor cause I'm not sure if that would affect the nonfuel prime and
