i have a 99 gsxr 750 that wont start. the FI light is blinking, and where the temp reads out says FI. i put a new relay, but that didnt help. and i raised the tank and took off one side of the fuel line. when i hit the start button, there is no fuel, any ideas what might be wrong?

its confusing me cause i rode it to work and it ran fine the whole way. stopped for a minute and killed it, then it wouldnt start again.

please help, i need this bike running. thanks in advance.
if anyone has an online copy of the gsxr manual can you please send it to me?

oh yeah, i used a volt meter and have power to 2 of the wires that are plugged into the fuel pump. dont know if that helps, but maybe. lol

sounds like it might be a cam position sensor, but your gona need a "mode selector switch" to get the codes from the ecm. I cant remember off hand the exact color codes but theres just basically two wires in a 4 or 6 pin conector in the back of the bike that needs to be conected using another wire or paperclip.

Try testing the cam sensor if you can the sensor should have around 1 ohm resistance and should push out more than .8VAC while cranking. Also test the circuits (wires) and conectors.

 

anyone know what colors? and how many pins?

 

nobody has any more help. nobody has a manual they can send?
