Sudden misfire and its not due to rain

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
