tiler, you are going to have to check every fuse and relay you can find in the car. also, make sure your grounds are clean and tight. if you get it going, then you are going to have to do a parasitic draw test to see why the battery died like that in the first place. fairly easy procedure with a multi-meter just google it.

A battery that reads 12.6 volts is not a good, charged, battery. A fully charged battery will read at least 13.2 volts to 14.4 volts. You need to do a load test to see what the voltage drop is. That is what tells you the condition of the plates in the battery. A used battery is just exactly that. A USED BATTERY.

The solenoid controls the power going to the starter. The ignition switch controls the power to the solenoid. That is what clicks when you have a bad (low) battery. Remember the car is computer controlled.

Have you tried shorting across the solenoid at the starter to see if the engine turns over?
