I think this might be the fuel pump problem again

Hi guys
We have had a lot of fairly unseasonal weather here in New Zealand recently, I know your hearts bleed for me, lol.
However I left my 2004 GS1200 out in quite a few heavy rain storms and this morning I took it up the road only to have the engine die on me a 100 yards from my house.
I can get it to start up, turns over for 10 seconds then dies.
Do any of you fine people think that this might be the famous electronic fuel pump controller issue, or does the fact that is starts up the dies point to something else?
Any input gladly received.

Cheers

Jon
 
The symptoms mirror those exactly that I had when it was the fuel pump controller I'm afraid.
 
If the fuel has run out on one side of the tank the jet pump wont have any fuel to extract the remaining fuel from the other side. So fixing the FPC wont help until there is more fuel in the tank.
 
Mine did the same in Scotland in heavy rain last year. I took the FPC out and found that the rain had seeped past the sealing gasket and filled up the space underneath, once i'd dried it all out everything was o.k.
 
Cheers guys

OK, the general consensus is that its the dam fuel pump.
Its the same one from new so I suppose its just one of those things.
But really appreciate your feedback guys, thanx.
By the way would highly recommend NZ for a bike holiday.

Might be that the hole the FPC fits in is full of water and shorting the terminals (rubber seal twisted or something).

If you fit a replacement part, cut up the old part and make yourself an emergency bypass cable to keep on the bike. Handy should it occur again, or you happen upon another 1200 rider stranded somewhere.
 
Well no joy with that.

Eventually got the bits to do the workaround, plugged it all in and could hear the pump working which was a bit of a relief.
However when I started it up I got the same outcome, runs then dies, and now battery is flat.
Don't suppose this could have anything to do with the battery could it?
Again any feedback gratefully received.

Regards

Just for peace of mind is the fuel level low but not empty ie still showing 60 miles? Try putting some fuel in it may be a weak fuel pickup problem.

Thanx for the pointer Barney, it wasn't a silly idea as the fuel gauge is not quite as accurate as it once was.
Unfortunately still no joy.
Can't work it out, battery good, tried the work around, that runs the fuel pump, I can hear it when the ignition goes on, however every time I start it, it runs for about 10 seconds then dies.
It does sound just like fuel starvation, however, when you turn of the ignition key then turn on again starts first time, no stutter nothing but then dies.
 
The rain might just be a coincidence, there has been a lot of it about lately.
Possoble causes include fuel pump as well as the filter, or even the pressure relief valve.
Pattern pumps are available on EBayf for £30-£40 these days, pressure regs are around the £50 mark. Not cheap to experiment with. Got any mates whose bikes you borrow bits from?
