You're doing yourself a disservice by piggybacking on this post, especially when there is no usable information to use for a diagnosis. Only the three of us will see your question. You should start a new post so all the experts will see it and have a chance to respond.
Also, when you have an engine running problem, please list the engine size, the type of transmission, the mileage, and a complete list of symptoms and what you've checked so far. Things like "doesn't start" and "hard starting" can mean dozens of different things. We don't know if there's a starter system problem and the starter doesn't crank the engine, or if it cranks fine but doesn't run. That's like saying "I'm in pain; why?"
The only thing I can guess from the original post is perhaps fuel pressure is bleeding off. It's a simple matter of connecting a fuel pressure gauge to see what happens one minute, one hour, and one day after stopping the engine.
