It sounds like the tank is being pressurized. Check that the vent pipe from the tank is blocked.

I have read that these prolems might be caused by the carcoalcanister doesn't work properly. This canister is connected with the intake via a temperature switch on the cooling water system. You will find this valve if you read about the evaporative system in Haynes book. Check the temperature switch too. If it doesn't work it might not open for the fuelfumes to come to the inlet manifold. I don't remember where I have read this. It was on another toyota site. I hope this will help you.
