2011 Husaberg 570 Wont Start After Soldering Fuel Pump Wires In Wiring Harness

Hope somebody can help.
I had to solder the 4 red and white wires in the wiring harness under the fuel tank .
All went well pump primed everything good ,started up no problem .
I thought i would make sure it was a good soldering connection and soldered the wires well.In doing this i did not have the fuel tank on and it took a lot longer to solder .I had the fuel pump plug still connected to the relay when i was soldering and the light came on then off .
Now when i turn the bike on i put a blinker on and the headlight as well as putting the fuel tank back on.When i hit the ignition switch on the blinker comes on as well as the headlight just to make sure i have power to them but the bike won't start and the fuel pump isn't priming and as soon as i take my finger off the igntion button the blinker and the light go off straight away .
My question is have i damaged the relay or something else when i soldered the fuel pump wires in the wiring harnes without pulling the plug out from the relay.
Ive checked all fuses and nothing is blown.

Just thinking put needles in wires at both ends of the soldering and check with test meter. Pump may have Thermal switch of some kind I don't know this.

Ok, Something is up here. The soldering should not cause any concern to anything when joining wires. Unless you heated a electronic component that could not take heat, everything should work. I would take tank and seat off as well front plate. Disconnect each component. Then start one by one testing what was messed with. If the tank was off, I am to assume the pump was out of the tank to stay connected? check connections at pump to ensure no connection was compromised and is shorting to ground or power or is open. Ensure your four wire connections are not shorting to each other. Are the red and white wires soldered together the same way and not mixed up? Not sure of the model but sometimes same color does different things. Check any switch connections. Something might have been pulled or shorted together by heat down the wire when soldering, so follow the harness to ensure. separate every thing and test with tank off. A simple light in place of the two fuel pump wires will let you know if it is powering up. run direct power to fuel pump to ensure pump is working, could be damaged when it was worked on? This goes on and on so check even the things that you would not suspect as wiring can be funny and sometimes is not forgiving. Hope this helped and hope you find the issue. Please update and let us know
Thanks from tourist

Ok ,found the problem the ECU ,it must of got a spike through the line when soldering the wires which is unheard of but thats what happened.
Had to order a new ECU ,couldn't get the original in australia will take a month to get .
Got the upgrade ECU from vortex with the 10 map settings which you can do on the fly which is great.
Cheers for the advice guys.
Thanks from jon andersson

Thank you for sharing that expensive and unlike to happen accident. I will for sure disconnect my ECU while soldering from now on.

I would also go vortex instead of OEM.
