one off FI fault

[DavieSV]

Hi all

Went to jet was the bike (I know, wash by hand, but it still had muck from north wales 2 on it)
Pulled up at the garage, turned off the ignition, read the display on the jetwash and it said OFF. so I went to start the bike again (after only a matter of a few seconds), but the FI light started to flash, the engine would turn over but not fire.
I checked all normal starting functions like kill switch etc. All seemed to be in order. I tried in vain a few times, turning ignition off and on, side stand up & down, but nothing.
I pushed the bike e few yards out of the jet wash bay to where I could put my helmet down safely, took helmet off and tried again.
This time I could hear that the feul pump was not pressurising when the ignition was turned on. So I turned the ignition switch off & on a few times then I heard the pump start, thumed the button & started 1st time.
I have a meta357 (something like that) alarm fitted.
I have heard that security cameras and things like that can mess with the imobiliser. Is this true???
It hasen't happened since.
What do you think? one off glitch? or sign of things to come?

Cheers John

I think you just got a connector wet and when the excess water dried off it was alright.

I had a similar thing happen, actually I had an M357 meta on at that time too, I'd been out and there was a lot of water running down a hill near me, so for a good mile was in maybe 3/4" of water (and hot sunshine, typical)
Stopped at the local, when I went to start it the immobiliser wouldn't disarm, 20 minutes later after pushing it halfway home it started fine.

[DavieSV]

It was rainingg at the time and there was standing water leading into the forecourt, so that's probably it then

It puts my mind at rest a bit
Every time I turn the key, I think will it / wont it

Thanks for that:D

Cheers mate

[sv650nutter149]

yeah common problem sometimes with the svs they just dont like water.....

[DavieSV]

the down side of fitting a tail tidy then I suppose

[sv650nutter149]

tail tidy shouldnt affect it most propably front cylinder

[yorkie_chris]

Not really, that mudguard won't direct much away from the electrics anyway.

My immobiliser fault was with all standard mudguards (on curvy)

[yorkie_chris]

tail tidy shouldnt affect it most propably front cylinder

wet front pot stopping the fuel pump from getting power? Highly unlikely IMO

[DavieSV]

I manufactured my own tail tidy from stainless steel to fit on the orginal mounting holes under the rear panels
The alarm is fitted under these panels & I know that I did not profile the inner plate that locates into the rear light assemble correctly, so thare are slight gaps in the tiny panel on top of the tail under the grap rail.
If going at speed in the wet, no problem, you get the roster tail effect off the water from the back wheel, but at slower speeds the spray just covers the pillion seat.
Water can & does ingress here, so can get to all the electrics under the seat
I must look at the sealing of all these holes, some time:)

[yorkie_chris]

Silicone sealer in the gaps, and loads of grease or ACF50 in the connectors

[DavieSV]

is grease an insulator then?

[yorkie_chris]

Silicon grease is

[DavieSV]

Thanks Mate
I'll try that
I presume I'll have to search out all the resetting info for the alarm if I disconnect all the connections, right?

[yorkie_chris]

No idea.

I tihnk you can disconnect the battery with no problems, did have the manuals kicking about in pdf format, but cn't find them ... so go here:

Hi all

Now not one off:(

Happened again today about 11 o'clock in the center of derby
Clear skies, dry road
This time I was stopped for about 15 mins
I turned the ignition on and off a few times then heard the pump come in
So I'm thinking possible not the alarm??

Any ideas?
Ignition switch?? (lights & instrement display come on)
Relay for fuel pump?? (is there one?)

Cheers

Check the plugs & cables of the submersed pump, but after using a meta 357 in rain I would probably blame that.

I had a couple of moments where it let me down in heavy rain. funnily enough, it dries out and works perfectly again

I will at some point have a look at all my electrics to avoid water ingress

Hi Davey, sorry to hear you're having problems.

Isn't there a resistor or diode in the ignition swich that is there to stop hotwiring. Could it be that?

I presume if it was a problem with one of the cut off switches, clutch or side stand, you wouldn't have got a FI warning.

Good luck mate.

There is in the curvy, not sure about the pointy.


I'd start by bypassing all the safeties, they're usually prone to failure.

[DavieSV]

Hi all

Just took a quick look at my bike

All the safty switches just seem to cut the pump off but bring up no FI warning light
I dont know if one of them shorted it would do the same but as it is an 'intermittent' fault it is hard to trace
I will check the leads and connections to the fuel pump one night this week just to see if there is anything obvious

Othere than that just wait for it to become more regular then trace the fault

Any other suggestions welcome

I'll keep you posted

Cheers

Hi all, finally got a fault code

Bikes been a pain today, filled up with petrol then it took me 5 minutes to restart it.
Got it going and got it home.
S*d's law, all evening it's started fine.
At 8.45 to night, tried to start it and the 'click' nothing, then FI light.
Qucikly fitted dealer mode tool before the fault went again.

The code is c42 "ignition switch signal"

I'm going for a poke round to see if I can see anything obvious.

Any idea's are more than welcome

Cheers
John

Right then boys & girls

The bike is on the paddock stand in the garage, not even the wind could rock this thing.

When the ignition key is turned, sometimes it starts, sometimes not.
I've tried wiggling wires, but there is no difference.
I do put a squirt of wd40 in the ingnition switch when it gets stiff.
Could this oil have seeped into the "electrical" switch, taking all the c**p with it and therefore making the contacts dirty?
Could a coroded connection sometimes allow enough voltage/current, sometimes not?
Could it be the immobiliser at fault?

The switch must be getting a feed as all the other electrics come on.
The feed from the switch to the ecu must be the one with the fault I would have thought.:confused:

would the feed from the switch, to the ecu be cut by the immobiliser?

Grrrr:(

[flymo]

Three obvious things I can think of would be;

1. the ignition switch itself, good squirt of wd40 should sort that out.
2. The ignition switch connector plug, its tucked up behind the radiator. You can reach it best by wipping out the airbox but can also be got at from underneath if you undo the bolts and pull the radiator forward. Again a good squirt of WD into the connectors wont do any harm.
3. Less likely but I've seen dodgy connections to the ignition coils cause the FI light to stay on. If its just one coil then the bike might just start and fire on one cylinder. The coils are a bit of a bugger to get to as they are tucked down either side of the engine bay towards the rear. They have exposed spade type connectors and corrode up pretty easy.

Its more likely 1 or 2 I reckon.

[DavieSV]

Thanks mate

1, The ignition switch has had a good dose of WD with no effect.
2, I'll try and get to the front connector tomorrow, I've traced the wire but had no time to get the air box off.
3, I don't think it's the coils.

Once it's made the connection to the ecu, it's fine, it doesn't cut out while riding, it's just the split second after turning the key, I can hear the relay for the fuel pump click in and out again in a second, the FI light doesn't start to flash for about the time the fuel pump normally takes to pressurise the system then shuts off. The starter motor will still turn the engine over but not fire (no fuel i presume)

I'll see if the front connector brings any joy
