78 280z not cranking. not starting. please help

So i try to start up my 280z. When I turn the key nothing happens but a clicking noise on the passanger side by the fuse box. I believe the clicking noise is the ignition relay.

Power is getting to the car because when i turn the key i can turn on the ac unit. But the volts and gas meter won't turn on.

I replaced the starter in the engine and the ignition switch.

(I'm not to sure what to think of this. The battery is charged. But its not even cranking unless I manually touch the 2 bolt pieces of the starter in the engine to manually make sparks and start it but it just keeps trying to start like there is no gas!? I am lost!)

Thank you for your help!

Check your fusible links, and make sure they aren't crispy.

I would start with replacing the relay.

Think you found your problem.
You should have 4 fusible links in a 78...
It would appear you are missing your third red link (ignition switch) and a black link (Alternator & Ignition Relay)
But it also seems like where your back red link is in your picture, that should actually be a black link, and your box that should have 2 red links is just gone...

The fusible links have been bypassed (yellow wires). It looks like an inline fuse on the one yellow wire. Check that. Download the FSM and start checking for the cause.
