2007 Montana, hard start long crank

[Stoker8]

Engine started to have drive-ability issues a while back.

OBDII code P0335 and 336, so I changed out the crank sensor twice, still the same.
OBDII code P0341 showed up once so I changed it as well.

Checked all electrical connections I could get to and cleaned them.

Did a re-learn on the sensors with a scan tool, runs o.k until I shut it down and then it will not start until cooled down and the crank code is set again.

Any ideas?

Tks for your time.

have you read the other possibilities in addition to the sensors themselves ?

Thanks for the reply.

Yes I have read the links, the tach in the van instrument panel reads out RPM's but my ODBII reader does not?

I have the 5 volt reference voltage at the crank sensor plug.
