1992s13hatch

Ok do here's the situation my friend just did a rb20det swap to ha s13 hatch. It was running when we took it out of the other 240. Now when we try to start it it gets fuel and spark bit the fuel dosent get through the injectors. I've did a lot of research but it is either talking about these two green relays by the ecu that I can't find or people fixed the problem and don't talk how. Could someone please let me know what's going on it ran great. But now nothing
