Engine Not starting

My 05 Kia Optima will die if I remove the gas cap and then it does not want to start back up again once I fill the gas tank up. It will eventually start as long as I push down on the gas pedal. However, it will die once I put it into gear. Eventually it will start and remain running until the next time I get gas. What could this issue possibly be?

It could be a fuel pump going bad. What to do is check fuel pump pressure the next time this happens to see if it is within spec.

How would I check the fuel pump pressure? Someone also said it could be the charcoal canister being clogged? Thoughts?

How full do you fill it? Have you tried not filling completely to see if that alleviates issue?
