Does the fuel pump relay get burned contacts? I can hear the pump running correctly on turning on the ignition for about a second (no different from when it was working OK), and it stops when I pull the relevant fuse, so maybe Colin's suggestion of the internal pipe failure sounds plausible. There's no leaking petrol anywhere, so I think the external flexible hoses are OK. I think I have a spare relay, so will give that a go anyway. I'll get a better chance to work on it next week, so will report progress! Chris
