Suddenly the bike died and refuses to restart

[tyclyd]

After around 1000 miles on this years second trip towards Italy, I was riding today on the D925 just east of Lac De Roseland when my 2004 1150GSA just died on a low speed flat run and refused to restart. Checked all the fuses and relays etc but as the rain was closing in I managed to get a lift from a local 1200GSA rider to the restaurant at Col Du Pre and called the AA European breakdown number – within 60 minutes a mechanic from Garage Des Carroz turned up to trailer my bike to the garage and a taxi was called to take my young son and myself back to Albertville. Cannot fault the local services on a Sunday afternoon but am now stumped as to why my 50K reliable bike has just died with no warning on a dry run and will not start – any tips or suggestions on what I should be saying tomorrow to the garage please – I am thinking perhaps hall sensors given the symptoms and no warning of failure?

Does the pump prime up when ing is turned on? could check ing switch loom on left hand side as they are known for wires to break in loom mine did the other day..

 

[tyclyd]

Yes - thanks I could hear it and its the nature of the sudden instant death that intrigued me... cannot fault AA European Breakdown however they have been excellent.

 

[how much]

quick check for hall sensors is the way the instrument display does its start up sequence when you turn the ignition on..

"something" doesnt happen on the display like it normally does.. bolloxed if i can remember what as it was about 6 years ago when mine packed up and left me stranded on my 1150gs

AA man couldn't even be arsed to find out what was up..and decided to trailer it too... "my chosen destination"

Thanks - did not notice anything different when i tried to crank her over... just refused to fire after "stalling" on a low speed run over the dam at Roselend

Can you hear the fuel pump prime when you switch on? No? check the wires at the right side of the tank at the connector Corroded / broken

Now wait a minute If you can hear the pump run but she no go, this is messy and you need to be sure no one is smoking near you But slip the Injector out leave it connected and spin the motor over is it spraying and injecting? If yes then move to checking hall sensor arrangement

If no drain the tank and remove the pump assembly she may have blown a hose off in there I've seen that on two sudden stops

I can;t see Hall sensor doing that quick a stop unless the cable is chafed thru or teh bolt on the crank end has worked loose

Does it start now it's cold?

 

[tyclyd]

Thanks - she would not start from cold - just tuned over strongly with the pump running. I have my young son with me so the AA have taken us back to our hotel - I will have to wait and see what happens tomorrow now?

You better hope its not the hall sensor. They are all sqirrelled away in peoples secret drawers.
Ive been trying to hire/borrow one for the hols ( seeing that everybody who goes abroad this year is feckin-up their sensors) but everybody is pretending they havnt got one.

I'm just trying to embarrass someone enough to hire me one ...he he

Good luck with your problem

Gary Slip an injector back out from the throttle body and spin it over (No One smoking nearby of course )

If it doesn't spray it probably isn't getting pressure 2 options no signal from Mr Hall

and 2, what I think the problem is i.e. the fuel pressure hose has popped off

To further check Mr Hall, If you lift out a stick coil Do NOT pull the cable disconnect it first and then use pliers to grip the coil and pull it out, Pull out the plug, fit it in the coil and ground it on the exhaust press the button (use insulated pliers to grip the plug and hold it on the exhaust if your worried) and watch if if sparks regularly If it does? then I would suspect the fuel pump hose

A simple matter to remove the pump refit the hose and crimp the pipe clamp correctly check the other crimps too

Once you have the fuel pump flange free and raised an inch or so, there are 2 x small diameter hose just carefully slip them off (and remember to reconnect when you replace the unit) Don't let the techie pull them or they'll come off up higher and it's a bollix to get in at them!

Thanks Dr Farkoff

I did a swap on the fuel pump and sender unit about 10K miles ago - it was a really careful job by me so I hope the hose is not off the pump...

Back in the hotel now - always worse when you have a pillion and in this case the first time my young son has been all the way to southern France with me...

Thanks

Thanks

Gary

He's having an adventure.....he'll be loving it

Don't take any imaginary monkeys on your back.....just relax if you can, enjoy whatever happens with your lad and look on the bright side....neither of you are hurt, you're together and having a bit of a challenge.......use it right and this will be the best holiday he's ever had, he won't remember the negatives, he'll just remember the big truck, the joy when you get it sorted and the way his old man sorted it all out

Chill, and good luck

easy enough to check - see if any fuel pumps out of the petrol tank fuel line as you turn the engine over, doesn't matter which one, supply or return.

Or try clamping the fuel supply line and listen to the pump making a straining sound. If it doesn't strain you've lost the internal hose. If it does strain it's something else

Like the hall sensor

 

[richie]

Hall Sensor, it was said already but ....

Hall sensors do suffer from instant failure.

If it doesn't spray it probably isn't getting pressure 2 options no signal from Mr Hall

!

Sorry, but that's all bollox - you can still get a spark at the plugs, and a signal at the injectors with a fecked hall sensor.

Thanks Neil, I will check the fuel supply again tomorrow once i get back to the bike - pretty sure the pump was working however, just died instantly after a longish low speed run and climb up to 1800m, on the descent - thought it had stalled whilst moving but when I came to stop the bike would not start.

Thanks all for the encouragement - lad is in bed now so I can relax... lets see what the new day brings.

You talking to me?

 

[(RIP) DitchWater]

Another one!!!

This is incredible. I shouldn't even be looking at the internet now but riding my bike.

 

[Pekkavee]

When did you change your alternator belt?

I have seen this to happen to the Hall sensors.
Broken sensors

That front one by the fuel pump is actually a bit loose looking!

I did a swap on the fuel pump and sender unit about 10K miles ago - it was a really careful job by me so I hope the hose is not off the pump.

Steptoe has more time at these than me but I've done a right share of bikes and I've never really heard of Hall sensors just dying without some sort of messing around first such as flicking revcounters, misfiring, erratic running and also knocking the bollix out of some poor techie who was changing a known good plug into the spark plug cap just at the time the sensor decided it would be fun to start shorting out! for about 15 bloody seconds !!! DAMHIK!!! Needless to say Ignition is always completely off now if there's a chance of them being faulty! Feckin things!

No Matter what it is I hope it's a relatively easy fix for you

All of which is exactly what happened to mine
