FED UP!!..won't start - fuel pump controller?

[Zed3]

Just back from 3000 miles around Europe. 05 1200 GS fully serviced + valve clearances checked before I went. Came home from work yesterday and tank running low, but still showing I had enough fuel to get to petrol station in the morning so did not fill up. Arrived home showing 10 miles left.

Bike would not start this morning. Cranking over and trying to start and just about running on one cylinder, but no joy. Thought maybe there was so little fuel that pump was not picking it up. Topped up with 5 litres of fuel. Tried starting but again would only just about run on one cylinder (left)for a few seconds before stalling. Noticed that the dash display was still showing only one bar of fuel and 10 miles left. Also during the 3 or 4 attempts at starting the ddash did show a faulty front light (which it had done once the previous week. Lights not faulty and fitted with HID).

Checked fuel pump controller and there was some water collected but all contacts seemed dry and no corrosion. Sprayed with GT85 before trying to start again.

Had also noticed a "ticking/knocking" noise that appeared to be getting louder over the past couple of days that was difficult to pinpoint, but appeared to be coming from the right hand side, to the rear of the engine behind the RH cylinder - not from cylinder head.

Any ideas as to problem? Are these symptoms of failed fuel pump controller or am I looking for something else?

Any help/advice appreciated

Bad battery?

The fuel pump does not have to be wet or corroded.
They fail anyway.

If the fuel pump controller goes, it won't run at all - although it can be intermittent, I think it's an "all or nothing" thing. No reason why it would run on one cylinder.

Given the fragility of the battery, I think th efirst symptoms of a duffer are nto beign able to turn the engine ove rin the first place.

Could be so many things - my first port of call would be to check the coils. Other than that, I think a visit to the dealer is required. At least they should be able to narrow down any electrical cause by using their diagnostic thingy.

You can make up a test lead to put 12 volts straight from the battery onto the fuel pump, bypassing the controller, simply by crimping some terminals onto some old wire. I put ring terminals on one end of each wire to fit the battery, and an inline bullet connector on the other end to prevent shorts and allow me to push it onto the round headed contact pins of the fuel pump. You will also need a small Torx head screwdriver to undo the controller and remove it. The fuel pump will run continually but thats all you need to prove/disprove the function of the FPC.

Do a search on the threads to find which colour wire is +12volts and which is earth as I can't remeber off the top of my head.

If the bike starts and runs using a bypass wire (like mie did) then you know to go to a dealer and part with the cash for a new FPC. They aren't cheap for what they are !!

Have you checked you are getting a spark on all plugs?
Sounds more like a coil isn't firing to me.
