The fuel pump does not stop (570FS 2010)

Hey! I've got a problem with my Husaberg FS 570 2010. I had been out and run for an hour, suddenly dies. Drove up to the edge and tried to start it. Nothing happened! When I start looking, I heard that the fuel pump went and the smell of gasoline. I pull out the plug to the main relay. Then I try and press the start button and when I released it as continued fuel pump to go. Fuel injector was open so I filled the barrel with gasoline. Anyone know what the problem might be? Excuse my bad English, Hope you understand my problem

Seems like your fuel pump signal wire is shorted to ground. Fuel injector wires. One has 12vdc consistently and the other is signal from PCM it grounds when required to spray fuel. If this wire shorts to ground the injector will stay open and fuel pump continues to deliver fuel until it pressures up.

Just a guess but I would check and see if the injector wire has ground and if it does you need to follow the harness to find out where it is shorted.
 
It seems that EFI does not turn off Start relay.
When it works as it should, it is starting relay drawn about 3 seconds after you shut it off! Or, if you try to start it and it does not start then starting relay feature for 3 seconds. But now when I press the start button and pull the relay all the time. and I will draw out the fuse 1 to get shut of. Can they be something wrong with EFI?
 
Possible the control module is gone, but more than likely you have a short in the system. I am guessing that your signal wire is shorted to ground somewhere in the system. check the injector signal wire for ground. Take the injector connector off the injector. One wire should have consistant 12vdc. the other wire should signal ground in pulses. If the other wire is not signaling pulses then disconnect at control module and test again. If it has no ground then the harness is fine. If it has ground then you have a short. If no ground then chance it is your injector driver in the module or something else signaling the module to fire fuel. We can only give a direction but not guess as you need to do a step by step diag or you will be replacing everything by guess work.
I still believe you have a harness problem somewhere. I think this is a good place to start your diag.
