My 81' 280zx just stopped running while on my way to work.There is no whine (noise) coming from the fuel pump. Plus, there is no fuel reaching the injectors because the fuel line or hose, has been removed and nothing comes out when turning the ignition. Could it be the fuel pump or fuel pump relay? There are also 3 fuel pump relays located around the vehicle, which one is the actual fuel pump relay?

Thanks in advance,

Is that an internal fuel pump or an external? If it is external, smack it with a hammer at the same time you are cranking the engine.. This well get the brushes to make contact with the armature and fire the engine. Now if it doesn't start, that doesn't mean that its not the fuel pump but most of the time the fuel pump fails, this little hammer work will get it running..
