Typical crap chargecooler fault mate. Easiest way to check if the pump is working (ignoring the fuses for the time being) is connecting both terminals of the pump up to a battery and see if it powers up.

If that works, then I'd be looking at the chargecooler header tank. Check on the right corner where the hose connects to the header tank to see if you get a strong stream of water shooting through the port, if not then stick a pin in there as it can become congested over time.

Do those 2 things to start with, then come back to us

Alternatively, ditch the crappy system and get an air2air kit off me
