Hard to start Hot.

Hay Fellows,
I have a 89, 7.3 IDI, F250 and just replaced my Manual Fuel pump with a power pump. The truck starts up fine, right after the plugs stop cycling but after i go for a drive and shut her off she becomes hard to start and somtimes won't start! Is my new pump flooding the engine or is there somthing that might cause this other than the fuel?
Thanks

Unfortunately, starting fine when cold and hard starts when hot point to an injection pump ready to die.

Do you run any fuel system cleaners?
How long since the fuel filter was changed?

Hi Dave
I changed the the fuel filters and the water seperator only a week ago. As for fuel addatives i have been runing the Lucas fuel addative as our deisel here is the ultra low sulfer and i heard from a friend that it is hard on the older IDI engines.
Thought it might be my IP but was hoping for a minor problem, lol.

Since you eliminated the other potential problems, I am sorry to say it looks like the IP is on the way out.
