2002 MERCURY MOUNTAINEER V6, When fueling the vehicle, the fuel pump stops at about half fuel, and only by (squeezing) to fill up. I think the vent on the tank has a valve which is stuck closed. Also the check engine lih=ght came on a few days after the problem started. What should I look for first?
