Daewoo lanos has not had a battery in it for 12 months was running now has dash lights winds over but no pwer anywhere else and no fuel coming through

I just gone through this it could be a bad earth or engine stop relay mobilizer so you can sand relays and everything you can including battery take earth of battery for 20 seconds( negative) might start don't listen to sparky or he will put new pump scanner and everything you don't need think about it nothing has changed but time and corrosion and you might have to reset computer by 20 seconds negitive earth good luck. One thing i do know is when they were brought THIS CAR into this country they had a bye-pass anti theft device connected to computer if you lose or flatten battery to your key it will do all the above so you can buy this bypass device online and get sparky to install.It to the computer .And this will problem will be fixed for good hopefully .But i have fount no online memos about this as different teams added this device to your car for our lovely goverment
