It also never hurts to dig up a copy of the Factory Service Manual. It has complete diagnostics listed as well as a general list of possible causes:
Incorrect fuel tank vacuum relief valve
Incorrect fuel filler cap used
Fuel filler cap remains open or fails to close.
Foreign matter caught in fuel filler cap.
Leak is in line between intake manifold and EVAP canister purge volume control solenoid
valve.
Foreign matter caught in EVAP canister vent control valve.
EVAP canister or fuel tank leaks
EVAP purge line (pipe and rubber tube) leaks
EVAP purge line rubber tube bent
Loose or disconnected rubber tube
EVAP canister vent control valve and the circuit
EVAP canister purge volume control solenoid valve and the circuit
Fuel tank temperature sensor
O-ring of EVAP canister vent control valve is missing or damaged
EVAP canister is saturated with water
EVAP control system pressure sensor
Fuel level sensor and the circuit
Refueling EVAP vapor cut valve
ORVR system leaks
As you can see, there's no one simple fix.
