Engine does not crank after replacing the fuel filter?

I changed the fuel filter and unhooked some brake lines from the master cylinder in order to get to the fuel filter. It took longer than 20 minutes was able to get the old fuel filter out. Didn't leak much gas for what I expected it was almost 3/4 tank in there. Got the new fuel filter in there. The in house might be a little twisted or possibly crimped maybe in my effort to get it on. But in the end, I got everything hooked together as far as I know the battery, the fuse, the brake lines. I went to start my car and got no turnover at all. Lights up so it's not the battery it makes a little hum barely audible but doesn't turnover. Something electrical or could it be the fuel filter?
