Hadi:

Have you measured the OHMS of the coil packs at the spark plug wires?
I have a hard time believing that washing your motor could blow all 4 coils at once. (I won't lecture you for washing your motor, although I want to.)
So whatever it is, it's common to all 4 coils.
My guess that something has gone shorted to ground and you're losing some key voltage that the ignition system needs (although this should blow a fuse first).
Give the motor time to dry out.
Open the hood and let the motor get hot in the sun.
You could try to dry the engine by blowing on it with a leaf blower or careful use of compressed air from a compressor. You just want to dry it a little, not cause more problems.

Come to think of it, it could be a VATS issue, try a different key.
Try locking unlocking the drivers door with the key.

Check the IGN1 fuse for 12v with the key in the "On" position.

If you've got power there then the problem is either under the plenum or with the ECM.
