Sudden misfire and its not due to rain

[CRH]

How do I check if it's the relay or do I just Gabe to replace to know. I don't have a multimeter :-(

............right!!....firstly find the relay"..then unplug it and make sure all the contacts are clean..spray wd or whatever you got handy on it?....then plug it back on!!....then switch ignition on and you should here it energise ie click"....if it dont its sus??....if it does then bk to fuel pump???......

If you can't hear the relay energising, it's worth keeping a finger tip on it - you might feel it moving, if not hear it.

Ok so i can hear the relay energise so guess the pump is duff. I did bypass the pump in the end and the bike fired up first time so at least we know there's no wider issues.

Thanks for helping me with this peeps, having my commuter bike off the road is annoying. Seems like the pump is at fault so gonna get a replacement pronto

Too late, bought a used pump from fleabay now for £30, guaranteed at least

yes thats right...with both pipes removed it should click like crazy it will only stop when the float bowls are full and fuel pressure increaces,as you have disconected both pipes theres no pressure build up so pump will continue ticking.....to test the pump without the relay ,disconect the pump from the loom and run 2 fresh cables straight to the battery this will tell you if the pumps a good un or not.......hope that makes sense

Final update then....

The replacement pump arrived today and looked very clean and in good condition so pleased with that. Fitted it to the bike and it's all now working as it should do so problem solved 

I've even topped up the oil and set the tyre pressures as i want, cant wait to get the old girl back out on the road!!
