Hi Steve, I had a look at the elec dwgs this evening.
The large plug next to the relays ontop the ABS unit, 12v direct from the battery to term 9 will make the pump run.
Central Informer under the dash has 2 connectors, dead easy to remove and reconnect.
Also check relay 11 is ok, its the one that you use for fuse checks.
That battery +ve connection direct to the ABS unit is crucial, I would disconnect emery and re connect again. If all that fails I suggest a swap of the ABS box. If you need a hand then give me a call and I will pop over. 07973 933973
