No injector pulse

I just bought a jdm Japanese 2.0L motor,swapped the intake from my stock motor and a few other components, after getting it all together it would crank. But wouldn't start, after testing found that it had no spark or injector pulse, after doing some research found that the crank sprocket had different teeth on it for the ckp to pick up on. I swapped the correct sprocket and it finally started but has a dead miss on cylinder 3. It has spark but no injector pulse, it's getting voltage to the injector connector but the PCM is not grounding the injector for the pulse. I have a cam code even after swapping with a good sensor, I have not compleatly tested the ground wire going to the PCM but I was thinking maby the cAmshaft sprocket is different due to the crank sprocket different. Has anyone else had any experance with this issue or situation? Thanks
