FI Light Flashing

Hey gang,
On my way in my FI light came on. It did not flash...was constantly on ?

When I got to work, put my bike in Neutral to back in to my parking spot and that is when it flashed 1 time ? I put the kickstand back up and placed it in gear and the light did not flash but went constant.

My manual is on my home laptop so I can not look up the correct code. Has anyone else had this happen ?

According to the manual,
Stays lit: Faulty ECM or short in the service connector wire.
1 blink: Loose or poorly connected MAP sensor connector, Open or short circuit in MAP sensor wire, Faulty MAP sensor.
Now you can ponder that all day while you're at work, waiting till you get off so you can take a look at your bike.

I suggest you follow the ECU diagnose steps described in the service manual by short wiring the service connector, kill switch to RUN position and turning on the key.
Then you should see exactly which codes are stored in the ECU and pin point the fault.

It is described in the manual that you must have the engine in N, the side stand down and the engine's speed less than 5000rpm so that the FI indicator can flash the fault's code. If any of those two are not applied then you get a constant FI indicator on.

Check those tiny wires from both connectors to the ECU. I had same FI light issue and found one of the tiny wires broken on the grey connector - soldered it back up and FI light issue gone.

Hey guys...happened again last night

When riding my bike started to cut out on me but when given more throttle it smoothed out. The FI light came back on as well ! This intermittent stuff is killing me !!!! Also noticed a more pronounced fuel smell in the garage this morning, which is not normal. No gas on the garage floor though....Going to take her back in and have the wiring traced yet again...at this pint the only thing I know to do is replace the ECU and hope that's it...could it be the PCIII ??

I have replaced the following in the past months

Throttle Bodies
Fuel Pump

Need help gang...this is very frustrating !!

What the FI does does as your riding it likely means nothing. Do as Makis said with the service connector and the steps as per the service manual, and get the proper code. It's fairly common knowledge that the ECU will store the code, unless you unplug the battery.

Do the proper diagnosis and won't have to shotgun change parts.

You have changed TBs you said?

Some of the things you describe could be caused by a faulty TPS which comes solid on the TBs and cannot be adjusted.
Another thing that comes to my mind, reading your description, is a clogged injector....

Check the TPS's connector if it is properly plugged on and not corroded but it would me good if you had another TB set to try out. Just to make sure that they are not the problem.

I assume you've already checked the Fuel Pressure Regulator since it's a more than common issue on our ladies

I think this may be incorrect. I'm pretty sure the bike's ECU will store past codes until you go in and manually remove them. That's why it's a good idea to make sure you erase those old codes after you've solved the problem.
