Experiencing a hard start maybe 3 or 4 times before it starts. I replaced the crankshaft and camshaft but still same thing.

Hi,

The code could be caused by a few different things. First, the actuator could be faulty, not properly installed, or there could be a wiring issue. Also, there could be an issue with the timing chain or chain tensioner allowing excessive play in the chain and throwing off timing.

Take a look below at the diagnostics related to the code and let me know if you are comfortable performing the tests.

Take care and let me know what you find.
