Thanks again, its a case of stripping back the loom until I find a problem then?
I have my pump wired live so it will run regardless, would these fusable links be the ones located beside the ecu or am I completely wrong?

Also when I find the source of the melted wires will I need to find out what its connected to and replace/sort out that part or problem?
Wiring is not my strongest point so please bare with me here
