The original owners manual tells you where the relays and fuses are.

The two you're looking for aren't directly behind the glovebox, but removing it will make it easier for you to get to them.

The pump motor should buzz when the key's turned to position "I" - so you don't need to start the engine. If it doesn't buzz, you need to be checking the relay/fuse for the pump motor.

The rest of the system's turned on at position "II", so this is where the lights come on and the ABS ECU does its diagnostics.

Two of the relays for the ABS system have fuses attached to them, so they're easy to spot. The purple relay for the pump has a 30A fuse, and the green one for the rest of the system has a 20A fuse. There's also a third inhibitor relay in the fusebox but this is not likely to be your problem.

Most likely it's the 30A fuse for the pump that's popped. Mine did, and burned a hole through the fuse holder, so I ended up fitting a new one. Works like a charm now. Both the purple and green relay are about a tenner from Ford. Might be a bit pricey for some, but at least you're guaranteed the right one!
