Will it keep cylinders 2 4 and 6 from firing?

Hi,

A faulty crankshaft position sensor would prevent ignition spark to all spark plugs. As far as the cam sensor is concerned, no, it shouldn't cause this to happen.

Are you not getting spark to the plugs mentioned? What diagnostic trouble codes are present? Are they only P0302, 304, and 306?

Let me know. If you haven't already, confirm if it is a spark-related problem or if we aren't getting fuel to that bank.

If there is no spark to the plugs, note that those three share a common ground. It is G114 located on the driver's side rear of the engine. See pic below. Make sure that connection hasn't failed as well. It will shut down all three of those coils.

Let me know.
