I have no spark, and no fuel, will not start.

What is your question?

I replaced crank sensor, cam sensor, coil pack, checked timing chain ( good ). Still no spark or fuel. Found a white fusible link that was melted, there is the white one, and an orange one, that tie into a 10 gauge wire. I cannot find the problem, currently checking relays. Can someone give the info that I need, been working on it for two weeks to no prevail.
