Hello,

I have been a master mechanic for over 35 years and am happy to help with your question.

The hard starting and the 336-340 codes mean the cam and crank sensors are reporting a prob;em to the computer and should be replaced. Below is a diagram showing where they are located. Replace them and it will take care of the hard start issue.
