I thought i fix the problem i was having with the main relay. swap it out with a new one but still same problems. when i try to start it on cold start the main relay doesnt click on. found out that that im not getting ground from pin 8 that comes from the ecu. when i jump it to ground i works. it only happens on cold starts. it takes awhile turning the key to get it to start. also it has like a 10 second delay before it clicks on.
.1995 civic with a d16y8 swap.

also i added an extra ground wire from the battery to g101 ground and cleaned the pins on the ecu. hope it helps.. wouldn't be able to tell until the car cools down.

did it work?
right thing to do would be get a new ecu ,
but they are harder to come by now. So I wanna know if your ground fixed the issue so I can copy you
