Default 5.3 will not fire
Just rebuilt my 5.3 and I got everything ready to go. I turned the key and the motor just turned over and over. Didn't really get to check it out further battery died and got dark so I had to come home! Any ideas

I checked everything. I ended up pouring fuel in the tb and it started but I found the problem. I didn't have the the little hose that goes to from the intake to the fuel rail on. I guess that's to pull fuel up to the fuel rails
