Title: Fuel Pump Failure warning
Post by: Edgar on August 11, 2020, 10:08:04 am
So the weekend no problem with the bike. This morning when I wanted to start the bike I got a "fuel pump failure" warning. I can hear the pump is not pumping as it should. I check the connectors, disconnected the battery, but the warning remains and the bike won't start. Could it just be a dirty filter, or should I go and buy a tube of KY jelly? :xxbah:

Could be a filter for sure.

It's not THAT bad to check and change the filter, if you've taken the tank off before you're like 80% of the way there.

Do I have to take the tank off? Can I just remove the fuel pump assembly and buy a new filter kit at KTM?

You might be able to, To be honest I havent done it on a 1X90 but I did it on a 990 SMT which has the same sort of setup really.

You can see where the whole assembly pulls out of the bottom of the tank. Take a look and see if there's anything in the way of it being removed.  You will need to drain that side of the tank at least to make it less messy.

Thanks I will check. I recon if the crashbars are not in the way I should be able to unscrew and remove the pump that sits on the left tank  :thumleft:

I removed the fuelpump with ease without removing the crashbars.  Probably just dirty, mine does that when I drive very hard and want to start it again after a quick stop.  Til this day I couldn't find the problem. Still happens often

@TriBaldy and I removed and serviced the pump on his 1290 recently. A bit fiddly but easily done with the tank in place.
Don't forget to close the two silver fuel taps before removing the pipes, and keep careful track of all the O-rings as you go. Poor Tribaldy sat with a dead bike for a while because we got the o-rings wrong.

No need to remove the tank. The fuel pump and filter is situated on the lowest end of the left hand side of the tank. 4 bolts, disconnection of the fuel line and electrical wires and bob is your uncle. There is a video to do this on the web. It really is very easy. If you lay the bike down on it`s RH side then you don`t need to empty the tank.

Thanks for all the replies I appreciate it. On my list of to-do things for the week. Going to check with KTM for a new filter kit today.

@Edgar
got it sorted yet?

Consider fitting a Guglatech filter at the tank inlet - Pretoria fuel seems to be dirty at many garages

Jip, was not the fuel pump. Ground wire on the harness that shorted. 4 hours labour at KTM to locate the problem ::)
