What relay?

Use a voltmeter to measure the voltage at the battery. It should be 12 to 12.5 volts.

Start there

Ok, when you turn on the key, does the lights come on on the dash?

No nothing at all happens. Its weird though because every once in a lucky moment. Power comes on but the second I turn the key, theres a loud click and all goes dead again.

It sounds like a bad connection at the battery. Remove the cales, clean the inside of them and re install and see if anything happens.

It sounds like you need help from a shop and it gets a lot more complicated from here. Could be fusible links. If it is, you must find the reason it blew and that is a time consuming process.
