This is rather common and the easiest way to deal with it is to just turn the 
key ON and OFF a few times to fill the lines before trying to start the engine. 
If it is particularly bad you can add a pushbutton switch that will run the 
pump without cycling the key.

The problem is usually caused by gas boiling after the engine is shut down, 
leaving the system empty for the next startup.

Try this test: After shutting down for the day, go inside and let the car cool 
down for a few hours. Go out and restart it just before you go to bed, but let it 
run just long enough to smooth out, a minute or less. The next morning if it 
starts right up this is your probem. If this didn't help, then you have a different 
problem and will need to look into it some more.

In either case, any gas leak is a bad thing and will make this problem worse.
