Which relay is which ('74 260)

[orange260z]

Hey all,

I am trying to figure out which relays are for my electric fuel pump. I checked both the FSM and the Haynes manual, but neither has a "map" of the relay block. Can anyone tell me which of the 6 or so relays are for the fuel pump?

Thanks,

Ayan

I don't know if this is of much help but my Clymers manual shows two relays for the fuel pump . one shows a yellow and a black white and a black wires and is marked alternater they both show G W inter connecting both relays .The secound one has a black and black white and a yellow . It is marked starter . Hope this is of help. Gary

Hey Gary, thanks for your response. I'm trying to locate the relay without actually removing all the stuff in the area, so it's a little hard to see what wires go into what relay.

I was hoping that someone might have a "map" of the relays - ie a picture of the area with labels showing which relay is which, like a fuse box cover usually shows. Unfortunately, there doesn't seem to be such a map in the FSM, at least for the relays (there is one for the fuses, of course). Do you know from experience which relay is which?

Thanks for your advice as usual...

I'm doing the same thing on my 260. I asked almost the same question on zcar.com. They are located up above the fuse box to the right. Yup, in that wiring mess. Check out my post there. I got an answer about bypassing the relay, and which wires you do it with. I just might put in an aftermarket relay and wire it accordingly. I really see no need for 2 relays, unless one of them cuts fuel when there is low or no oil pressure.

Well, I was close about the second relay. One turns on when the starter is energised and shuts off when the engine is started. The other one turns on when the alt hits 400rpm. I believe the smaller one is for the starter circuit. In my case, both the elect and mech pumps turned out to be faulty. Just my luck, go figure.
