right guys after spending a over a week in the garage basically stripping my bike down coz it wouldnt start (BATTERY IN THE END) whilst waiting for a batt i took the fuel pump out and removed the paper filter at top of pump then put back together and forgot about it.. now the batt has arived and it did the trick the bike turns over (BUT WONT START) ive took off the fuel hose from the tb and cranked the bike but no fuel is getting there ????? the pump doesnt seem to be working how can i check the pump??????
Yeh checked that . Its good .... iv took the pump out now and it dont seem to be working ??? How can I tell ot test???
Fuse? Relay? Connector to loom? Electrical connectors to fuel pump right way round?
When you switch on, can you hear the pump priming?
Fuse is ok ,, dont know how to test the relay??? White plug to loon is 3 pin it only goes one way and is the only plug I know of ?? And there is 12v at the plug .... but dont know what the 3rd wire does and no voltage from it??

If, when you open the switch, you can read 12v on the pump wire leads......then it´s the pump...

if no voltage on the leads....then check the relay or fuse ( change them around to test ), maybe you moved something while doing the battery tango.....let us know after you test the leads going to the pump

EDIT : when you open the switch, does the instrument cluster turn on? are you shure the kill switch is not engaged?
ok so I made this little vid....try this...

using a Multimeter, set it on VDC, secure the Negative lead to a good grounding point on the SD

now disconect the fuel pump´s conector, and place the multimeter´s positive lead on the cable colored Black w/ blue stripe......open your switch....and you should be able to see 12v for about 2 seconds....if that´s correct, then re-conect the pumps conector and try again on the other side of the conector, on the RED cable....still see 12vdc? then all is good with the relay and fuse....and we got a problem on the pump side of things.....let us know...



EDIT : yeah, so I hit my finger with a hammer in the mornig....problem???
Evil... i think i love you LOL.

Yo evil right im getting 12v to the plug and the pump ,, the pump is out of the bike now to make things easy ?? Right I got a red and black wire (tank side of pump) the red gets 12v but so does the black????? Wtf ??? So when I earth the black wire to the frame the pump runs.... ??? The brown wire on the plug has a good earth
Oooooooossssssssssshhhhhhhhhhhh yeh shes alive :lol
Right anyone taking the fuel pump out be carfull of the little earth connector to the pump if it catches on the tank on the way out it pulls the wire and spade conector from under the pump in the housing but not visable till pump is taken apart !!!!
