Answer: KB,
Moisture in the gas tank is a common cause of hard starts. This occurs especially in the cold and wet seasons. Check your gas cap to be sure its providing a good seal. Most stores will sell an additive that will dry out (remove moisture) the gasoline in your tank. Check your local auto parts store and ask a store attendent to point you in the direction of the gas additives. Most are inexpensive and may help with your starting problems.
Good luck!
