friends 6.0 hard starting issues

[AKHILF]

My friend has a 2005 6.0 and one day he ran it out of diesel. He filled it back up and said it took him about 2 hours to get it running again. Now if the trucks cold it take a while to start, but once its warm it will start just fine. Whats your guys ideas? He dosnt have a scanner. Thanks for the help

Running a 6.0 out of fuel is very bad. It can mess up the injectors. How long was he running it on low fuel? Is it running clean and fine when its warm?

I wasnt there to see it run but he said once its started it runs just like always and is normal. He said if he lets it sit for about 6 hours its back to hard to start
