Describe "hard to start" a bit more completely.

If hard to start means that the engine cranks for a few seconds before
it starts....and only does this after the engine has been off for a
while, the next time you try it first turn the key to the on
position but do not try to start. You should hear the fuel pump
run for a couple seconds and then quit. If you can then turn the
key off and back on and it starts, you have a pressure leakdown.
