Disco 2 - fuel pump problems??

Hi
I have a 2001 Disco 2. When I was driving to work yesterday the engine cut
out and after pulling to the side of the road I found the engine would turn
over but would not start (or even try).

Whilst waiting for a recovery vehicle I checked all the fuses and found the
30amp fuel pump fuse was blown - but when I replaced it, it still would not
start but did not blow the fuse. After getting the car home, when I tried
today the fuse did blow. So I've removed the leads to the pump and the fuse
still blows??

Feels like it might be a cable shorting somewhere?

Anyone any similar experience or could suggest where the cable might have
rubbed and shorted?

Thanks
Ian
