Dd got some from amazon USA- we aren't so lucky cause amazon don't sell outside USA :(

Is there a particular website where I can buy those links from Nissan?

Replace the fusible link, they may look fine but are quite easily broken inside.

Also check the earths. I had similar issues last year

Check all the earthing points, clean and tighten. They can cause funny issues. Then do as DD says, trouble shoot. It'll help if you use a wiring diagram and trace through the system. Trouble shooting wiring can be time consuming but it's better than being stuck somewhere.

another weird thing: when this happens my headlights work, but the turn signals dont. What could that be? This is why i think it has something to do with a fuseable link that has more than one power type running through it.

You can buy a fusible link from Nissan, they are not expensive. But those look OK.

What I would do is troubleshoot the problem. Does the ignition switch have 12V? When you turn the key to Start, does 12V get to the starter small wire? Track it down.

This wiring is a mess. I think these fuseable links should be replaced, but im not sure if i can pick up some generic parts at autozone to make it work. I had a problem a while back with my car not starting. I sprayed some contact cleaner in random places and it started up. It's been running fine for a few months now. Until yesterday. Now it's doing it again and it's almost a matter of luck to get it to start. Any suggestions?
