Hard to start after injector pump belt replacement

[palmtree]

I just had my IP belt replaced in a shop. The car runs fine but is a real pain to get started in the morning. Before the belt replacement the car always started almost instantly. Now it cranks for what seems like forever before it will finally start with some depression of the accelerator. I never had to touch the accelerator pedal to start it before the belt replacement. I am pretty new to this car and diesels in general. Is there some kind of adjustment he made when replacing the belt that makes it start different from before?
Thanks
