Another wiring problem. No ground.

Ok, i hate writing this because its covered everywhere but my bike is just not exactly doing the same as everyone elses. So here is the deal, one day my bike just dies on me and i get it home to the garage. after taking it apart i realize the fuel pump isnt kicking on. so i test the pump by hardwiring it and its good. then i test the relay. its good. i just hardwired the fuel pump and tried to turn it over and still didnt start. while im doing this i notice im not smelling any gas so the injectors are not operating either. and just for the hell of it i see if its getting spark and its not. after troubleshooting for a bit i discover everything is getting power like it should but nothing is getting ground. i test the four wires on the ecm that go to ground and they are good. i test the power going into the ecm and its getting power. i then test the wire going to the fuel pump relay from the ecm that gives it ground and it has no ground and i also cut apart my harness to make sure the wire was good and it was. and to confirm that the relay was still good i hard grounded the relay and the relay clicked and turned the fuel pump on. but im still not getting any ground coming out of the ecm. now im about 90 percent positive its the ecm but there is still that 10 percent that im not certain of. so my question really is does anyone have a layout of the ecm pins so that i can test each individual one to confirm my theory? or if anyone can give me 100 percent confirmation. im really sorry for posting this guys. dont hate me. i just cant find anything on here about it.
