If you have melted wires there then you have possibly melted wires somewhere else. If the pump won't prime maybe the fuel pump relay? Worst case the ecu or a hidden bit of wiring in the loom.

There are five relays under the dash on the drivers side and a relay/fuse box in the bay.

No mate same part number etc exactly the same there was a dead short across it my fault for not putting a multi meter across it before I fitted it bought it on faith but should have tested it hoping it's the relays or a fuse I've missed
