yes i can! its under a black cover next to the airflow meter (under bonnet mounted to passenger side inner wing) lift cover off and you'll see 3 relays,2 orange and one either white or green,its one of the orange ones,if you look at the wiring going to them its the one with green/purple coloured wire....just found this out myself a few days ago! whats your problem?

fuel pump in the tank wont run when you turn the key on to feed main pump, pump in the tank works fine coz we've had it out and tested it. just wondering which relay powers it up? fuel pump relay or acu/dme relay?

[telski789]

fuel pump relay,the one with green/purple wire going to it,take relay out and get a piece of wire,put it into the pin numbered 87 and the other end of the wire into the pin with number 30,this will run the fuel pump continuously,if it doesnt then fuse number 11 in the fuse box is probably dead,it should be rated 15. if these dont work your pump is kaput...

,it should be rated 15.

It should be rated 7.5A!
Finding a 15A fuse fitted here is a sure sign of a failing fuel pump. The stall current of the pump is sufficient to blow a 7.5A fuse, but not normally a 15A one, so when the typical muppet finds a blown 7.5A one blown afew times, he 'cures' it by fitting a 15A one.
