ZXRs have a problem in that the fuelpump only operates when the starter button is pressed, I'm pretty sure they're supposed to operate when the ignition is turned on but I've had 4 or 5 L models over the years & on all but 1 the fuelpump only worked when you hit the starter.
The simple solution to your problem is to bypass the fuelpump relay. Get 2 pieces of electrical wire about 250mm long, strip the ends a bit & put 1 end of each to the battery terminals, follow the 2 wires from the pump & unplug the connector then stick the other ends of the wire into the plug + & - your pump will then pump for around 5 - 10 seconds until it fills the carb bowls (you'll hear it slowing down to almost nothing when the bowls are full) then plug the pump back in, ignition, choke, hit the button & you will be smiling.
Be warned though, ZXRs are notorious for electrical gremlins, starter relays, fuelpump relays, dry solder joints & dodgy switchblocks all make for interesting ownership.
