my cbr 600 f3 (96) was running fine one day and just stoped the next, it turns but wont fire i checked the main fuses, plugs have a sparkand installed a new pump cause it seemed to not be pumping. i made an open tank and hooked it up and the new pump isnt pumping i seen that on the newer bikes they have a fuse to the pump. i looked in the book for this bike and didnt see anything like that. i have no clue..... do you

ps. what is a (b.a.s.) and is there one on my bike.

 

dont know, good luck

 

you could try checking the wires to the kill switch cause if the kill switch is off the pump won't work, so maybe you could have a bad kill switch, just a thought
