P1446 is evap leak code. (vent control valve to be specific) you will need a new vent control valve and water separator kit installed. About $215 for the parts.

    Awesome thanks so much this vehicle also has a big problem with accepting the fuel when trying to pump gas it keeps backing up i was wondering if one thing had to do with the other , i really cant figure it out its like there is just too much pressure in the tank while the gas is going in.

    replace the vent valve and it shoudl pump fine. sounds ike yours is stuck closed and the vapors are not escaping causing the pump to shutoff. replace dvent valve and install water separator kit.
