2004 Honda Odyssey is hard to start. I replaced starter and still has the problem. Normally after it parked for long hours especially overnight. but it did happen every morning. when it happened I pump gas then eventually it would start. I replaced fuel pump yesterday. This morning I got up to start OK. An hour later it hard to start again. I have to give some gas. What's the problem?



How good is your battery?

Or is your air filter clean?

Check your battery. Go to the nearest autozone and have the staff check your battery. Overtime battery looses its capacity to hold charge. If its not holding most likely its power depletes out.

I had Auto Zone to check the battery and it was bad. After replaced every thing works fine. Thanks.
