How do I fix my Chevy?! Well what should I try next?

I recently got my truck back from the impound lot
and they left the lights on. After a week of sitting
there, the battery was dead. I had it jumped, it
made it home (about 4 miles). I turned it off, had to
get another jump. Made it 2 miles down the road,
realized it was out of gas. Pushed to accelerate
and it popped lightly under the hood. Got pushed
to the gas station and put a little gas in ($5 then
$2). Still didn't start. Pulled it home, checked, fuse
to the ignition blown. I replaced it now there barely
a flow coming from the fuel pump. I also noticed
my boyfriend forgot to put the gas tank lid back on.
I asked him to pump while I checked the engine.
The pump is brand new and I got a new battery
too. What can I fix next? I'm running out of ideas
and low on funds. I don't want to keep guessing
but the fuse was needed and so was the battery
and fuel pump.
