Location of All Fuel Pump Relays- 79 280ZX 2+2

Need help finding all the fuel pump relays on a 79 280ZX 2+2. I've ordered a Service Manual from Courtesy Nissan won't get here until next week, but need to work on the Z before then. I know there is a set of relays under the hood on the passenger side, but they are not labeled as to which is which. There's also a set of relays under the passenger seat, same thing, not labeled. I'm not getting fuel, but I've tested the fuel pump, checked fuses, checked oil pressure sending unit, and various other things. But trying to follow the wiring diagrams from these cheap autoparts store service manuals is like reading Japanese and they are never right. You get what you pay for. Any help will be appreciated.

Thanks,

Funny you mention about reading japanese. Guess what the manual is translated from... You'll find descriptions like the datsun Z's tailgate (hatch) and others. LOL

For testing relays, what I generally do is find two that you know are good. Swap them out with suspected bad ones two at a time. When the problem relay is narrowed to two specific, you just swap one, if it still works great then the one left in your hand is the bad one. And vise versa.

Redhawk, does the 79 also have the one behind the glove box like the 82/83 zx's have? If so, both relays are green, the one behind the glove box is, of course, the furthest one in along the passenger outside wall. Be prepaired for scraped knuckles.
