08 Saturn Aura Won't Start

I while back I broke my engine, so part of it had to be rebuilt. Now that everything is back in place the car won't start. It sound really heavy when trying to start and the starter gets super hot. We found that if we remove the spark plugs from the side of the engine that had the work done the car starts smoothly and stays on, but as soon as we add at least one spark plug back it doesn't start again. Any ideas what the problem could be? I bought a brand new battery hoping that was the problem, but no go.

Okay, after further testing I found that the 3 coils on the front of the engine give no spark, but the other 3 coils do. It seems that they do get spark the first time you try to turn on the engine, since it turns on for a second than dies out. Then after that it just doesn't do anthing, is there sensor that can cut off the spark to the coils?

Turns out one the timing chains was off since they used the wrong marks.
