I just put and rb20 in my s13. Its out of another s13 that I rode in and it ran good before I got it. Plugged everything up and it won't start unless I spray starting fluid in it. If I don't spray starting fluid it kinda sputters like its almost starting but never will. Its getting spark and injectors are firing. But how much fuel should I see coming out of the injectors? Its basically just a puff of misty fuel from each one. I have an aftermarket fpr coming out of the rail from the front of the motor, set at about 40psi. And ecu is throwing codes 31 "ecu" and 34 "knock sensor". I'm not really sure what could be causing it to not start. Any ideas?
