car is a 96 integra with a jdm b16b swap. had it running and pulled the swap out to clean the bay up and swap my tranny along with clutch and axles. now that i put the swap back in it doesn't want to start. I am getting fuel pressure spark and my timing is on point.


i decided to check voltage on my injectors and have now realized i am not getting ground to them(signal from ecu). so my question is what would make the ecu not send a ground signal to the injectors? i would think maybe a broken wire but i have no ground to all four. what can i check out or look for? im confused and out of ideas, I've checked all my grounds and even added new ones. also swapped ecu on it.

when i did this it gave me a ground signal at the injectors so i tried to crank it and it actually started to turn on but then stopped and just the motor would spin. once it did that i checked the injector siganl again and no more ground signal.

any help would be greatly appreciated guy!!
