Hi,

When cranking the engine, does it sound normal? In other words, do you notice any difference in the sound or speed the engine turns?

I ask because the sensors you replaced are relevant, but there are other things that may be causing the issue. My biggest concern is if there is an issue with the timing chain.

Is it possible for you to record it cranking and upload it for me to hear? I should be able to tell if it is timing-related

Take a look through this link as well, you may find it of interest:

Let me know.
