So i got this real rusty Datsun 1978 280z. Has the l28, and the 5 speed. Im getting 35 PSI of fuel pressure, fuel pumps brand new, but it won't start. Runs off starting fluid, but no fuel is getting injected. I checked the relay above the hood release and it clicked when it was hooked up to power. What now? i found some more relays over by the fuse box, but have no idea what they are for. I can't find a wiring diagram either for this model. I need it running asap. This things kinda sketchy lol. I just need it to start so i can sell it

Injector relay, ecu, distributor wiring.
FSM will have the diagram as well as troubleshooting instruction.

So finally found the relays on the fender. I put a battery charger to each of them and they clicked so they're all good. I liked at that fsm thing. Other then the ecu, what should I check that has to do with injector pulse?

It's the ECU. I've had this exact issue with 2 other 280s
