I Have a 78 280z. It just stopped running the other day. Refuses to start. The fuel pump is not working. So i replaced it. Still the same thing. I can pop the fuel line and get nothing with the engine cranking. Is there a fuse or relay im missing? I have a haynes and its about useless. Thanxs

yeah there is a fuel relay in the passenger side compartment (or atleast thats where it is on my 260z), it may be bad. If you have any books, lookup how your ignition wiring is setup, and you can easily find where your fuel relay is. if you cant find it, i can hunt down some books to see where its at.
let me know.

Check the easy things first, like the fuel filter...if it's clogged up you will get no fuel to the engine.
