Fe570 2012 dead fuel pump?

Hi, after riding my Husaberg FE570 for about 2 hours yesterday it started to run lean, I tried to fix this by redoing the Grease around the air filter seals.
After that the bike seemed fine again, but after about 1 hour it started to fuel cut and sputter/back fire After stopping the bike and rechecking the air filter the bike would not start. I can comfirm that the fuel pump does not prime at all, but the wierd part is that the FI light is giving the Fault code for a bad Coolant sensor? Anyone have any idea why this is happening? My plan now is to replace the pump, but i was just really confused why the FI light is signaling for the Coolant sensor .
Anyone have any idea what it could be, or what i should check?
Thanks for all answers

As a counter measure, have you ever cleaned your injector and changed the thimble filter at the injector?

No Yesterday was my first time riding it after i bought it
Now the FI light blinkes 1 long and 1 short blink? Not a code listed in the user manual

If it were me, I'd start by replacing all the filters. Pull up the injector and clean it. At this point you know your filtering is up to scratch. I bought another quick disconnect off eBay so I could fit one end to drain into a container. Hit the start button and see if you get fuel.

These things are usually a process of elimination and you might as well start with those that need servicing.

so the diagnostic tells you coolant sensor, but you want to change the fuel pump?
Thats funny.

thanks for the morning laugh !
Not sure why I was thinking along the lines of
Check coolant level
replace sensor
check wiring integrity

PS do you have 13+ volts on the battery ? its not dying before it finishes the fault code flash is it?

Yeah i plan to do all that, the thing is just that the pump is dead as well, so im 99% it needs to be changed as well

[Edit] After double checking the battery does seem to cut of before the FI light is done flashing

Haha The reason why im pointing towards the pump being the problem maker is because its dead, as in not priming or making any sounds. The FI light does no longer give the Code for the coolant sensor, it now signals a code that does not exist(1 long blink and 1 short)
I have checked the Coolant sensor and liquid level

After a double check It seems like the battery cuts of before the FI light is done flashing I also spotted that one of the terminals is really messed up Although it seems to have alright contact since im able to turn the motor over all the way until the battery is dead.

If you read his post better it may have prevented you from being a smart arse...maybe not.

"There is a 6 pin plug under the seat that is not connected to anything. Take the cover off the plug. Short out Pins 5 (Black/White Colour wire) and Pins 6 (Brown Colour wire). That will turn the ignition on and fire the EFI ECU up. This must be what the XC1 tool does as it plugs into that connector.
You can do a test first and pull out Fuse 2 (Fuel Pump Fuse) before shorting out pins 5 and 6 and you will see the FI Light flash the Fuel Pump error."
