Engine won't crank and battery drains quick when turning ignition.

I changed fuse 104 in power distribution box for front power seat and changed spark plug wires because #4 wire had a short and already fried one coil pack. When attempting to start I had full power but engine would not crank. The battery is being drained quickly when attempting to start or leaving key in on position for a short time. The battery checks good, starter checks good, replaced the electronic ignition switch and no help. I switched all relays to see if one was bad but no good. Security system disables properly. The ABS plug which is on recall and was suppose to be replaced the first time it was in had brake fluid on it so I used air hose to blow out fluid and reconnected it. I have checked every wire possible to see if I had knocked something loose and found nothing. Any assistance would be greatly appreciated.
