Hi again all. I've only just had a chance to put your very helpful advice to the test, with fairly positive results - So when I bridge terminals 30 and 87 in the lower of the two relays, the fuel pump whirrs and the engine will start. However, I can then only stop it if I pull the bridge wire out - the ignition switch, stop switch and sidestand cut-out all have no effect. The relay I bridged has all 5 pins wired up and the two terminals I bridge have red wires. The other relay under the side cover is an identical component, but only has 4 of the pins wired up and no red wires at all, I assume this is the side stand switch relay. As an experiment I swapped the two relays over as it would be fair to assume that the chances they would both fail would be fairly low. The fault remains if I do that, but again if I bridge the lower of the two relays, the engine will start. That suggests to me that although the fault is related to the fuel pump relay, the fault is not in the relay itself. Before I waste money buying a new relay that I don't need, would it be right to assume that the fault is likely to be in the power supply to the relay? All the fuses are intact and everything else is working. Is there a way that I can check that without stripping all the casing of the wires to trace an individual wire through all the connectors. If the power relay is working OK (as I guess it it must be) could the fault only be in the wire from the power relay to the fuel pump relay. I've got a 12v circuit tester but no other electrical test equipment. My other question is that if I wire a manual kill switch into the wire I use to bridge the 5 pin relay would it be OK to ride the bike like that, so I could get it to a dealer with the right equipment to check the electrics over? Any advice would be much appreciated.
