I'd disconnect everything except the LED's and just run the code that
blinks them. If this fails delete more code and test again. If you do
this until there is no more code left and it still doesn't run (sorry),
you may have connected something up wrong. Have you got floating inputs
on the unused pins? Can the battery supply enough current to run the
circuit AND relays. Are your pin IO directions set correctly? Did you
set the correct oscillator fuse? Does your code jump to a non existant
program address? The list can go on forever.

Try starting with smaller code fragments and circuit blocks, then build
it up in stages. It will be easier to fault find.
