Lil troubleshooting help

[mrhino]

need a little help pointing me in the right direction.

TBI 350. had dead battary I left the key on all night last week. Then put a cheap little charger on it all day. had enough juice to fire it up. backed it out of the garage. left the charger on it for a while. Started it back up to put it back in the garage. It started spiting and spuddering, wouldn't stay running, final died and would not restrart. It just cranked and cranked. I checked the tbi no fuel at all from the injectors. (pump is running) shot a little ether down the TBI still nothing. checked spark. no spark. figured this was all from a week/dead battery. So I got a brand new one. still no spark or fuel. so far I chased it down to no power on either end of the ignition fuse in the fuse box. My mind has gone blank at the moment and can not think what would be causing no ignition and no fuel. unless it wont inject fuel with out a ignition source any help would be greatfull
