Long cranking time when hot... Isn't that backwards?

[Jason]

Since I have been daily driving the volvo for the past few days (finnally got it licensed) it cranks for quite a while when hot before it starts. If you shut it off and go to restart in within a few seconds, it fires right up. If you go inside someplace, or it sits for a half hour or better, it cranks for a long time. The engine is still warm, and I'm not getting any glow plug light. My experience has always been that these engines start more easily when hot if they are low on compression, and have a hard time starting when cold. My car starts instantly when cold, with no excessive smoke or stress. I was wondering if the problem was related to having the pump turned up, since its pushing more fuel. I tried pressing the accelerator down part way and that made it crank longer it seems, so I'm thinking too much fuel is the problem. My turbo diesel jetta had the pump cranked and I never had any hot start issues. I'm sure if I wired up a jumper switch to be able to run the glow plugs for a few seconds it would start, but I shouldn't have to do that with the engine hot.

Thanks for any suggestions.
