If the check engine light is on, take the car to an autoparts store and have them use a scan tool to retrieve any fault codes stored in the computer. Most autopart stores offer this service at no charge. There could be a problem with the evaportative emission control system. There is a charcoal cannister that stores gas vapors and when conditions are right, a purge valve opens and the vapors are used in the combustion process. The cannister can get full of vapors and if the valve/solenoid is bad, it cannot purge itself of the vapors. Also integral to the system is the gas cap. A faulty gas cap can cause problems within this system. I am not saying that the evap system is the cause, but the pressure build up in the tank makes me suspicious. Get the codes read and it will help narrow things down for you. Sure hope this helped and best wishes.
Try replaceing the fuel filter and check the fuel line to see if there is gas on the engine filter is under the frame drivers side and the plastic clips mave have broken off and may be leaking gas. This is dangrous...
