Discuss the causes and fixes for P0321 Volkswagen OBDII Code

I have changed the all 4 spark plugs, alternator ,mass air flow sensor, all 4 ignition coils and the crankshaft sensor and the car sounds like it wants to start i don't know what else to do can someone tell me why
-
I have had the engine speed sensor and the crankshaft position sensor replaced, yet the engine will not turn over. While the engine seems strong when attempting to start, and I assume replacing the connector to the above sensors is going to be difficult for this layman, would anyone suggest I try replacing the battery?
-
Let me check if there is any more information. What model and year is your vehicle?
-
Well, the spark plugs, alternator, mass air flow sensor, and ignition coils have nothing to do with the P0321 code. Now the Crankshaft Position Sensor is by far one of the most common problems that could trigger the P0321 code, but in some cases, the Camshaft Position Sensor could also set the code. Other than those two components I have not seen any other setting the code.
-
So I should replace the camshaft position sensor then I should be straight
-
I can't tell you for sure, without testing your vehicle, that the problem is the Camshaft Position Sensor is the problem, but according to the factory service manual that is the next step.
