Your fuel pump may be working to build up pressure but the check valve may be allowing the pressure to bleed off when you shut the engine off. This will make starting difficult.
An easy check for this is what rangererv said. Turn the ignition on without engaging the starter. Leave it on for a few seconds then turn it off. Cycle it a couple times like that, then try to start it. If it fires right up, it is most likely the check valve in the fuel pump is not working properly. The only repair for that is replace the fuel pump.

My first thoughts were what Gary said. That's the first thing I'd try. Turn the ignition on/off a few times. This will make positively sure it's getting pressured up.
btw, I had a similar problem once. I'd do the fuel pump priming thing and it would start everytime. In my case it turned out to be a plugged fuel filter! That one caught be off guard. I really didn't think that would be it.. but it was just a simple filter.
