You checked the battery it is ok at 12.66 volts after getting rid of the surface charge. You hear the fuel pump prime when you first turn the key on. Turn the key off wait a few seconds turn it back on and hear the fuel pump prime the system again. You can do this a few times to really load up the system if you want. Still won't start but it IS turning over. An often overlooked starting aid is the spark voltage relay in the engine compartment. It provides full battery voltage on start to the coil. After the starter is turned off the voltage is resisted down to 7 or 8 volts. This is almost a necessity for very cold starts because of all the drag. This circuit is often forgotten about and it becomes weak or non operational. One way to go around the circuit is to take a jumper wire, connect it to the double plug-in side of the ignition resistor and then to the positive jump start post. The resistor is the thing that looks like two cigarettes together mounted on the fire wall by the engine compartment light switch. That will give full battery voltage to the coil. Try starting again.
