I am currently away from my FSM- how many relays are there for the fuel pump? 83 na 280zx

 

There are 2 relays that work in conjunction, one for the fuel pump and another of the EFI, strictly speaking there is only one, but the FSM covers troubleshooting both if you have issues, that is on page 95 of the "EFEC, Engine Fuel and Emission Controls" section, at least at a quick glance the best info I could drill down to

 

here is teh page I referenced, if you need more posted so you can see them on your phone, just ask, Ill do my best to assist
