Did you unhook the EST wire ? Tan/black stripe.

Possible, your ballancer has spun the outer ring. Sometimes it happens.

timing is set to 6 degrees btdc with the esc bypass wire disconnected. shut off, reconnect esc bypass, plug negative cable to clear code. If vehicle doesn't respond well the problem is somewhere else.

Double check to see that you have your light connected to the #1 spark plug wire.

Go to a Discounter and buy a Piston Stop Tool (maybe 10 Bucks). Thread into the number one hole. At TDC, see where the mark is on the Balancer.
