The next time you start it, turn the key on, but don't crank, or start it. Then turn the key back off. Turn the key back on. But, again, don't start it. Turn the key back off. Now, start it. If this helped, your fuel pump is allowing fuel to flow back through it, bleeding fuel pressure. Cycling the key, with out attempting to start it, cycles the fuel pump, and builds fuel pressure.
