Mate of mine has a yonks old Yamaha Genesis. The fuel pump stopped working\nand he assumed it had something to do with the relay.\n\nYesterday I took the pump apart and the contacts were a bit shite, so I\ncleaned them up, adjusted the spring a bit, sprayed the whole lot with\nswitch cleaner and tested it. The solenoid activates, pushing the contacts\napart, but the solenoid stays activated. I can clearly see the gap between\nthe contacts. I don't know how many bikes have this type of non-return pump,\nmaybe someone here knows if there is a pump available these days to replace\nit? I'm assuming that either the insulation around the contacts is no longer\ninsulating, or something is wrong inside the pump body, leaving the solenoid\npermanently connected.\n\nWhat say those that know?
