Technical Stilo JTD ignition problem

[stiLLdon]

Hello everyone,
today I have replaced my headlight washer pump, windscreen washer pump and disconnected and reconnected everything in front driverside doors. After I wanted to try everything out, after I turn ignition key, every light in the car starts blinking, and also you can hear samo relay ticking fast (related to blinking probably) from engine. What could I have done wrong?
Car wont start, after I try to start it, it just drains power and restarts blinking (which stops after like 10 seconds, then I get all possible error/fault messages, including loose connection).

Before that everything worked perfectly with no problems whatsoever,

One more thing, i dont know if that is relavant or not. Before those errors, when i was testing pumps, i got EBD failure error... which i thought will go away after few starts, so I didn't bother with it, since everything was working.
Thanks..

Did you remove the battery connections when you removed the pumps ??? Check that they are back on securely Regards alsimmo

Connections are secured on the pumps. I tried disconnecting main battery for 15 minutes but still nothing. Mybe somethign went wrong when i reconnected pumps with ignition key still on? Could there be a fuse problem? 20A fuse in the engine compartment for headlight washer pump in intact..

Make sure that the battery connections are pushed firmly down onto the battery terminal posts and are tightened up very tight ! If the terminals aren't secured properly it will give you all sorts of faults Regards alsimmo

Battery connections ware pushed all the way down and tightened properly. Becouse I'm running out of options, I took out the battery and started charging it.. maybe that would solve the problem.
I couldn't measure voltage becouse my multimeter's battery's went dark

I tried disconnecting both pumps, but problem didn't go away.

alsimmo, thanks again for your suggestion, empty battery was the reason for everything, couple hours of charging and everything works fine, including both pumps
