Answer 1

P1345 Crankshaft position  to Camshaft position correlation

This code you can get if the distributor is installed wrong.

 The first step is to set the number 1 cylinder to top dead center

 With the distributor cap removed, locate where the igntion rotor points to, it should match with the distributor caps position for number one cylinder, from the inside.

Here what happens when you remove the distributor, it moves 42 degrees  counter closkwise, so this means you would have to move it 42 degrees opposite when installing.

 The rotor position would have to be where number one is at on the distributor cap
