    I have a 08 maxxforce 9. When engine is cold cranks perfectly fine. Once the engine gets hot and I turn it off and try cranking it, it won't start. Once it cools down it will crank right away. I already changed high pressure pump which comes with the low pressure pump and icp new. Internal oil leak somewhere? What's the most common factor?

    You are using the word "Crank's" --do you mean to use the words --{when cold, it cranks and starts fine --when hot it cranks fine but wont start }?
    Just need to verify if its a cranking or starting issue.
    If its a hot "CRANKING" issue --i would suspect the starter is hanging up when hot !

    80% chance of a blown out oring on the high pressure manifold on top of the injectors. Very common.
