2010 Duramax no crank no start

Ok, I have a 2010 chevy buswith a6.6 duramx diesel. The problem happens out of nowhere. If you shut the bus off and leave come back to start it it wont crank at all. No codes are stored starter is new and everything checks out! Any ideas?? It starts after a while again then it happens again

Of course with any start problem-- check the batteries-- They are wired in parrallel so you need to isolate one to test them.

Be sure all the connections are tight and clean.

I vagely remember there was a problem with the LMM not starting-- and GM had a re-flash for the system-- I searched for a TSB, and could not find anything. Might check with a dealer.

I think that is the code-- and what I was trying to remember-! I will check over at another place--

Here is a contact -- direct to GM Customer service-- they might be able to help.

Were are you at?
If it is losing communication with the Vehicle security module then it could be the IGN switch, or just something throwing the program loopy. Check all the fuses with an ohm meter or test light when it does it again. You could be losing connectivity when it is warm. Does the bus have an alarm on it or possibly a saftey switch that will disable it?
