shooting it with a gun
alternator or bad wires

If you have a new pressurised water system there is a possibility that the added water pressure could cause a leak.
Dead Battery. Are you sure your battery can maintain or hold a charge?
Not connecting it
The transmission leak should not have affected the way the engine starts. Repairing the transmission leak should not have affected the way the engine starts. A new battery should only have IMPROVED the way the engine starts. If someone was not careful and allowed a small particle to get into the fuel line as they were re-connecting it, it could certainly block the injector and cause starting problems, especially if it's a throttle-body (single injector) injected engine.
Use battery load tester and properly test battery. When battery fails, replace it.
The old starter might of blew your battery. I would either recheck the wires to the starter make sure I did it correctly and if you did I would buy a new battery. I JUST had the same thing happen. 79 bucks for a new battery just cause its "special" really sucks!
It won't. Look for a light that is on or a stuck relay. Also a dead cell in the battery will cause it to run down overnight.
You may need a new battery.
Spark plugs don't smoke. A bad alternator would cause a dead battery.
Dead cell in the battery or corroded or loose battery cables.
