HelloCustomermy name isXXXXX you for choosing

Ok....Here is the crankshaft timing marks.

Crankshaft rotation is clockwise when viewed from in front of the crankshaft pulley as shown in the generic image.

And this is what I got on the distributor:

NOTE : The Distributor is located in a fixed, non-adjustable position. No attempt should be made to adjust the engine base timing by rotating the distributor. Attempting to do so may result in engine cross-fire and mis-fire conditions. Timing is not adjustable.*

*Ignition timing can be changed by reprogramming the PCM using Techline Information System 2000 (TIS 2000) PC, and the Tech 2 scan tool.
Please contact dealer for necessary updates and procedures.

Let me see what else I can dig up on this distributor issue.
