    I'm getting quite close to (hopefully) running my '81 ZX for the first time, but I'm having concerns about how I've run my fuel lines to the fuel rail. Since the fuel rail I mounted needs to have the fuel pressure regulator mounted elsewhere, and I can't find a location for that, I stuck the...

    Hello all! I am new to the Z world and am almost done rebuilding my '83 zx but have hit a roadblock getting the fuel injectors to work... When I turn the key to run position, I can hear the fuel pump and injector relays buzzing and clicking erratically (honestly sounds like they're speaking...
