Check your main connection from your wiring harness to your coils. It is between number 3 and number 5 coil if i'm not mistaken. If its been unplugged before it may have come loose if you didn't put the safety latch back in place.

I had that problem once, and narrowed it down to the main plug to the coils. Water had gotten in there, and there was buildup from moisture. The easiest way to determine if it is the connection, or not, is to switch the coils from one side, to the other, and see if you still get the same codes, or if it switches sides.
