F800R 2013 Fuel Pump Failed in full flight!

[Snorton Norton]

Has anyone else had problems the fuel pump, does it happen a lot?  I was in mid curve when I lost power and that was it, won't start, no fuel pressure. Are these parts hard to get everywhere, BMW has none in Canada it seems?  Thanks  :)

Morning Snorton Norton

 

Are you sure that it is the actual fuel pump & not a lack of 12v to the pump?

 

 

There is a fuel pump controller  (Fuel Pump, Electronic)  on top of the pump pass-through assembly, if that fails the pump won't run.  The fuel pump controller  (Fuel Pump, Electronic)  regulates power going to the fuel pump so if it fails then no fuel pump run. 

 

If you know someone with a GS-911 that should show a fault code if the FPC (Fuel Pump, Electronic) is bad.

 

You can jump 12v directly to the fuel pump as a test (by-pass the controller) but you really have to know what you are doing to do that on the 800 bike.

 

To answer your question, yes, I have seen a few F800 fuel pump failures but those usually appear  shortly after taking the motorcycle out of winter storage. The F800 fuel pump is not anodized so long term storage with E-10 fuel in the tank can cause pump issues.  

 

The pump assembly on the F800 is expensive so you really want to test & diagnose it before tossing an expensive new pump assembly in. 

 

I have seen good used F800 pump assemblies show up on E-Bay. 

 

If you have a little automotive electrical  background you can unbolt the fuel pump controller  (Fuel Pump, Electronic) from the top of the fuel pump assembly, then unplug the wires from the bottom of the (Fuel Pump, Electronic), then jump 12v directly to the (red) &  (brown)  wires going down to the pump to see if the pump will THEN run.

Thanks, I was watching the young mechanic test the pump by applying power directly to the contacts under the electronic bits on top, the owner called me away before the test. Hmmm?

I appreciate your help, right now I'm waiting to hear from the shop, depending on what they say, I might pick up the bike and DIY it.  I'll update on the result.
