So i have searched all i can and ran every possible test am i Have come up with nothing Anyone with a wiring diagram or a way to test the fuel cut relay? or any other info would be grwatly appreciated Heres what is going on

Machine was running great went out riding all weekend didnt give me any problems than about 3-4 days later was having hard time starting but did end up starting ran ok for aout 30-45 min around yard work than died and would not start so i took i towed it up to the gargage Pulled off the fuel line going to carb and i am getting no fuel. Both the fuel pump and relay were replaced withing the last 6 months, Tested wires to fuel pump for continuity from the fuel relay and both were good tested for power at the relay and i am reading 14 volts, but no fuel Pulled the wires to the pump and put a jumper from blk/br/ tho blk/bl and tested wires at fuel pump and i have 14 volts there so all wiring seems to be ok. Then i jumped a wire from positive on battery to blk/ble on fuel pump just lightly and fuel pump works if you pulse the wire so i assumed it WAS THE RELAY bOUGHT THE NEW RELAY PUT IT IN AND i AM NOW IN THE SAME SITUATION NO fuel Nothing pump still apears to be ok and will sometimes give a quick squirt when you turn off the key Anyone have any idea do i need a new pump as well or could this be something else?

What is the blk/yellow wire to the control unit for? Should this have power? Does it control the fuel pump in any way?

Thanks in advance
Bob

Ps i just noticed no spell check on here i will try to to better next time

 

spellings usually no prob.. i have found on several models that the fule pump can read goog voltage but still not operate properly. what i have always done is put a new fuel pump on. if your wireing is good and you are getting an ocational squirt from the pump, then i would say your pump is not working the way it should.

 

put a load across the power supply to the pump eg a light and at the same time measure voltage if voltage drops then you have a wiring problem of maybe a fuses sometimes ive had it when a fuse is blown but not fully blown and when you put a load accross it the voltage drops away. hope this helps
