The pk3 system has a sensor ring around the lock cylinder these go bad a relearn will not fix this because no security code is being sent to the pass key module.

Line up the hole in the cam sprocket with the mark on the crank. if your facing the motor front, the keyway will be on your right, with the hole another 90 degrees around. I recommend using a ruler to create a line from the center of the crank hole to the top of the cam sprocket.

Have your crank sensor checked. After running hot it will extract.When it cools down it expands therefore it will start again.

8 degrees before tdc

battery is dead or too much corrosion on the terminals.

Change fuel pump relay.And check the fuses
