good - I'd try to prove if it works now. if you have a multimeter, check if there's power to it when its cranking. If there is, I guess that proves the pump is duff. if there isn't, then you're going to have to trace back to the fuses/switches/relay that turn it on.
(might also be worth powering the pump direct from a battery or jump leads just to prove it is definitely working.)

mine is 94 RRC, from memory is behind right hand foot well panel near throttle pedal, possibly yellow. when you switch ignition to on you should feel it click on momentarily then off once it has primed.

Click to expand...

very easy to check relay as above, and you won't get dirty either.

relay is under seat one with white and purple wire other relay provides power for it and ecu so both have to work (you can feel as well as hear click)they should come on for 4 sec then click off until you turn to start, they are 30 amp relays,are a common fault

It might be worth checking the inertia switch. I am guessing they left it under the front passenger seat on the later Classics.

You should be able to hear the relays when you turn the ignition on - should be at least three relays going click: Main EFI power relay, Fuel pump and I think the other is the ABS power relay. Don't confuse the ABS pump for the fuel pump, you can easily hear the abs pump but I never hear my fuel pump.

Great advice chaps, thanks. And useful too: there's no clicking from the relays.

Update: the relays are clicking into life so it appears to be a pump problem.

Could be the pump but could be ECU, bad earth, broken connector in the loom - the list just goes on. (sorry fella)

One other thought, if it is not getting fuel have you checked the wire from the coil that goes to the ECU - this triggers the injection pulse so if it is broken, disconnected or otherwise not doing its' job then you'll get no fuel.

No, but I'll give it a try. Thanks for the advice.

This is thoroughly ****ing me off now.
