06 750 li crank no start when warm

[allikanes541]

I have been having a long start problem on my 750li with around 120k miles. When I go to crank the car right after driving, it usually has a long crank, taking 2-3 tries to fully start. After a couple hours, or the first time driving my car of the day, it usually starts fine. DSC light on. I already tried changing the fuel pump fuse as I thought that's what it was. Any ideas?

How old is your Integrated Supply Module (IVM)??

not quite sure. I wasn't the original owner of this vehicle, but was a fleet vehicle so I expect it was maintained well. I have seen some stuff about the IVM I feel like the weirdest thing to me is that it ALWAYS starts perfect right after putting gas in it. It makes me believe it is something with the fuel system, but I don't have any problems when driving. I've been thinking about getting a new IVM, just don't know if its worth it.
