FI Light on after bike is turned off

Hey guys. My buddy and I are trying to figure out a problem with a 2003 CBR F4I. The FI light came on, and it stays lit after I turn the bike off.
If I recall correctly the light wasn't on when I was riding today only when I turned the bike off and it stays solid red when the ignition is off and the keys are out of the ignition. I took the seat off and disconnected the negative on the battery (don't want it to kill my battery). I checked the fuses, and couldn't find any blown fuses...
Anyone run into this before? The speedometer is not working (the digital gauges) - could it have something to do with that?
Any help is greatly appreciated.

might wanna carefully check the wiring harness leading up to the dash and look for rubbed/bad wires

Take the fairings off and the whole nine?

might as well. Its the easist way to start looking. Doesnt take too long. I'd start by concentrating around the forks and look to see what wire bundles move when you turn the handlebars left and right. Maybe something slipped and is rubbing the forks or triple tree.
The other thing would be to figure out how to read what the FI code is. Not sure if thats something you can do yourself or if it requires a special tool.

download this, its eh service manual for 01-03. Check around section 5, it explains the FI procedure to look for codes, as well as everything else you might wanna know about the bike.

Well I seem to have another problem now. Hooked everything back up and now when I turn the bike on and flip the switch, the fuel pump doesn't kick in.

You mean you dont hear the noise it usually makes? If thats the case, make sure the fuel pump plug isnt loose, thats the loudest part of the FI system.
See if that manual says anything about it as well.

Thats underneath the gas tank correct?

i think so yeah. The manual I gave you should tell you. Just follow to fuel hose from the fuel tank and see where it goes.

Well here is where I am now.
I have a bike in peices on my garage floor.
The bike will turn over, there is power to all the lights ect.
If I turn on the kill switch I do not hear the fuel pump engage. I checked the connection underneath the fuel tank and the connection looks fine.
I don't know where else to go from here...
:(

did you try seeing if there were any FI codes stored?

If I am reading the manual correctly its saying I need to have the engine on for the codes to flash. I can't get the fuel pump to work to get the engine on to get the codes it looks like.

doesnt need to be running.
Ignition Off, short the diag connector under the seat, ignition to On, run/stop to Run. the light should start blinking if it has a code.

do you have a voltage meter to check for power at the pump?

How do you short the Diagnostic connector?
I have a pocket electrical tester, has the red and black prongs with the sharp tips. Will that work? It looks like it tests a number of different things.

Ok I set my electrical tester to test OHMS and I put the positive side on the Brown Wire (middle connector) and the Black side on the Green Wire (left connector) and the needle shot over. The tester I have measures DC V, AC V, OMH, and batteries. Should I use a different setting?
Does that mean there's power?

you short the diag connector just with a piece of wire. For most other testing, use the meter on DC Voltage.

I just got home from work.
I'll go set the meter on DC V and see if I can get anything out of it. I think I have some old speaker wire laying around here.
Dude, if I can get this fixed because of your help, I am FEDEX'ing you a 12 pack of whatever beer you like. LOL

Ok dude. Good news, I got the bike running.
I went and bought some general purpose wire and I shorted the diagnostic connector like you said, only this time when I turned on the bike...I heard a distinct "click" from the rear cowling...Thinking that was odd I turned on the switch and my fuel pump started right up. Turned on the bike, no problems, took it for a spin around the block, no problems and more importantly no FI light while the bike was running.
The moment I turn the bike off the FI light kicks back on but its really faint.
I included a picture to show you what I mean.
And heres a picture of the bike for shits and giggles.

well, at this point, I would say that its either a bad wire, or some weird resistance....
There is a White wire with a blue stripe leading from the Dash to the computer. This is the wire the lights the FI light.
Now you what what wire to look at specifically. See what you can find.

Ok, I'll take a look tonight when I get home.

Well I checked both wires at the front of the bike comming from the gauge cluster and under the seat going into the main circuit connection. I didn't see a loose wire or fit on any of the wires and I didn't take all the electrical tape off but I ran back a few inches and didn't see any wear on the wire.
My gauge cluster doesn't work. The N, and FI light's are the only thing I see light up when I turn the bike on. I think the RPM needle is supposed to jump up and then back down and it doesn't do that either.
I can't take the front cowl off again (it was a BITCH to put back on, lol) until the weekend - should I take the gauge cluster apart? What would I look for if I did?

hmmmm....
as far as I know, yes, the needle should jump when you start it, kinda like a self diag. Have you unplugged any of the connectors to see if there is any corrosion in them? Also, maybe something wiggled itself just loose enough that its not visably loose... so unplugging, checking, cleaning, replugging seems to be a good place to continue, especially up near the gauges. Check the computer plugs as well. Might wanna check everything you can reach now, and if still no good, take off the front cowl and check in there.
I'll browse through the F4i manual and see if I find anything useful.
How long have the gauges been acting flaky?

I just bought this thing and the original owner said they have never worked.

well thats unexceptable. Lets get these things workin. I'm going through the F4i service as we speak.
