Hey everyone!
I’m looking for more info on the blink code I got on my 2018.5 fc450 FE.
I rode my bike today, after letting it sit for about 5 or 6 weeks while I was out of the country (honey moon)
And while in my 2nd moto I landed from a jump and it felt like the bike ran out of gas.
It’s giving me the 4 long and 1 short blink code.
I looked in the manual and that says “fuel pump relay or fuel pump controller.“
Has anyone else had this issue?
Any quick fixes I should check first?
Any help would be appreciated!

Our 18.5 KTM FE fuel pump let go at 40.0 hours on the nose... Did not get a code though, just quit pumping....

Yeah I forgot to mention the bike only has 19 hours. When your pump let go was it similar to how I described?

It started bogging on the track. Brought it in put on the stand and it wouldn't crank back!

The relay is located in the air box. If I remember right, it’s a purple plug. Pull off the cover, and it’ll be just above the filter towards the back of the air box. I’d try swapping that out before anything else.

If Husky put them somewhere else, someone please say so. That’s where they are on my orange bikes.

Yeah I posted this same question to the guys at thumpertalk and they suggested starting with the relay.

I ordered it today so I’ll updated if that fixes it!

I’m curious if anyone else that had a relay go bad got the same long 4 and 1 short x FI blink code?

I’ve had one go bad and I believe I had the same code. I’m not certain though.
