2012 Ford Fiesta - New Engine, Harness, Sensors, and PCM - Still Crank, No Start

P0340 is certainly a reason why the vehicle isn't starting but it indicates an issue with the camshaft position sensor rather than the crank. You really need to check the output of the camshaft ...

I doubt "intake" air is the problem - diesels will run on very wide air/fuel ratios. Perhaps there was air getting into the fuel system, which can cause improper injection and failure to provide fuel ...

My 2002 95 v6 saab wont start
