Fuel Injection light on 954 fireblade

[Steve R]

My son has just bought himself a 2002 954 Fireblade, with PowerCommander 3(not a USB model), after about 5 minutes of riding the warning light for the fuel injection comes on, if you stop turn the bike off and start it back up, warning light is off but comes back on after a minute or so. The bike still runs fine all the time the light is on. Any ideas what the cause might be and could this be related to the PowerCommander. And any thoughts on who is best to sort this out. (dealers in the country are pretty low tech affairs.)

Have you got a work shop manual for it. That will have the reasons for a FI light. I have a 954 with a power commander and this hasn't happened to me. If you haven't got a manual ,PM and I will give you my email address and burn you a copy. I have it on CD and also a manual.

Do that self diagnostic thingo and see what it comes up with.

It should all be in the manual

Hi Steve R, yes, from experience with owners of 1000rr's I know powercommanders are known to show trouble by way of the FI light, but you need to work out if it is the PC3 or not, so...

First things first, unplug the PC3 then run the bike in the same manner as indicated the problem, does the light come on? If not then its likely the PC3 and a Dyno tuning centre like Birdman45 here (doin' bikes) will be able to help (most likely) esp since hes a Fireblade king.

If the light stays then post up, hopefully also a bit of digging into the web will unearth a 954 specialist site you can ask that question to, but first things first, unplug and see.

All the best

Thanks for the help so far, I did plan to disable the PC3 to see if the problem went away. The bike had been dynoed in Bathurst (before my son bought it) to get it running right. Will certainly look up Birdman if I can't fix the problem myself.

(Edit)Son is happy to spend a reasonable amount of money for someone who knows what they are doing to fix the problem, although he is just finding out how expensive getting set-up properly with gear and bike and bits can be. (going to bike show this w/e to buy his own helmet, leathers, boots, gloves etc). So I can have mine back.

I've seen this before......It's your PC mate.I bet the FI code will show up as a injector or air temp fault.
Did you put the pc in yourself? & where did you get the map?

If you can't spend the money for a good tune/map,just disconect it mate.

[jasonbw]

Cheers Jace, he did say above the bike was bought with it in... prob wasnt done right? whats the cause of the FI light, is it from the PC3 not being tuned, or does it happen when the PC3 actually goes faulty.

P.s. No worries Steve, yep I figured since you mentioned the PC3 you were putting that on your 'to remove' list when fault finding.

I think he mention in his post that it was a pcIII not with a usb:confused1: ,but that should'nt matter.

Yeh if its faulty, it will throw a code,but most of the time its because people think they can just download maps from the web,but there is more to it then that.

[Kimbo]

Did he buy it from a dealer? If so it is up to the dealer to repair it under second hand warranty.

[Steve R]

No, a private sale, an aquaintance, and we know the bike has been well looked after, has just had $800 spent for 25k service (sighted rec) including a full set of braided lines and also came with brand new stickered and painted race glass, 3 spare sets of tyres, carbon yoshi slip on and the PC3, he had also just spent $1100 on suspension and just happens to weigh within a couple of kilos of my son.

[jace]

Mate.... get on the dynojet web site & download a map to suit those mods,but make sure its for a Euro ecu not U.S.

[Steve R]

O.K. Fault still appears with PC disconnected, and another symptom, fuel pum seems to keep running after initial prime. Any ideas before I take it to a specialist, could it be a clogged fuel filter affecting pressure or just a crook pump.

[jasonbw]

Not sure about the 954, but with my old ZX12 the pump did the initial prime, stopped, when the bike was started it started... and that was the way it was meant to be. Maybe the 954 is meant to be like that? (running once the engine is running)
To check the pump (without doing a flow rate test) go for a fang and rev it over 8K, try to get it up to redline (once its warmed up), if it hesitated, coughs and stumbles when it gets high in the revs it could well be a flow rate issue, where the pump is not supplying enough... that happens as they get old (or if the stocker is used for NOS kits that want more than the std rate I guess).

I'd still be hitting up a specialist 954 site with these symptoms. Anyone know of a good 954 site? you could try 1000rr.net but it wouldnt have much.

[Kimbo]

Just a quickie. It's a fuel injected bike so the fuel pump will always be running to pressure up the whole fuel system. Check around the airbox for any loose wiring etc. There are a few sensors around there. I you want Steve, flick me your address and stuff [ you have my email address]and I will burn you a copy of the Official Honda manual and post it to you. Don't worry about prepaid boxes and stuff . I think I can afford a few bucks to get it to you.There is a a bit on the fuel system and trouble shooting the system and codes.

[Steve R]

Just out of interest what temp do you think the bike should run at, even on a short run of a couple of k's its running at 87C and a longer run at 96C manual only gives a range min to max.

[Kimbo]

Normal running is around 81-85 but once you slow down or in traffic it climbs quickly to 100 then the fan cuts in and then out

[jasonbw]

I'll second that Kimbo, thats what my 1000rr does almost exactly.

Wont the standard computer hold the fault in its memory,maybe having to be re-calibrated or put back to basic settings??
Kimbo is spot on for the temp,mine does exactly as he describes

[Kimbo]

Hey Steve. Sent the cd this morning so you should have it mon or tues. . it will probably be something simple. Check all the connectors you can see around the tank and airbox. Anyway hope the manual helps. I am at work so I don't have your email address here.Mate i'm glad I could help out.

[Steve R]

Thanks again to everyone, especially Kimbo for the CD will let you all know the outcome of further investigations once I get the CD.
Upside is that the bike seems to run fine and apparently has for some time. Also found out that the local dealer tried to fix it with a new oil pressure sensor. Havn't talked to the other local dealer that dynoed the bike yet.

[Birdman45]

The fault code is the important thing, it will tell you exactly what the drama is. Just have the fault code checked, (any dealer can do it) and see what the problem is. Go from there, don't start chasing fuel pumps and flow rates, I am yet to see a bike stuff up coz of low fuel rates (stock bikes, I'm talking) and have seen guys pull their bikes apart in search of the worste, only to find a dodgy ecu, or something simple was the problem. Good luck

Thanks Birdman, We now have a copy of the service manual and can look for the fault code. The bike doesn't seem to be suffering any problems at all, the young fella took it for a longer run on sunday (100+ k's) and it ran perfectly. Still want to get to the bottom of this though and if we can't sort it will give you a ring to book it in.

I have a 954 myself, owned since new. Only time I had an issue was after getting it serviced, the FI light was flashing. The dealer couldn't fit the bike in for at least 2 weeks so I picked up a Haynes workshop manual & checked out the coding. Turned out to be the valve from the exhaust to the airbox need re positioning. (I have no technical words / ability)

On the GP trip had the blade hunting (surging) ay different times. Still havent figured that one out though it hasn't happened since. It's strange because once you get the bike up to about 7k revs it goes like a rocket, anything under & it was a bitch to ride. Made for some interesting riding on the Bonang Hway etc :mod_smilie_rockwoot :mod_smilie_rockwoot
