SOURCE: my car just failed smog emissions test, had high
i would put a good tank of gas in the system. like 93 super.drive the car for about 1 week or at least 100 miles. i would also go to a good auto parts store.u should be able to buy a bottle of engine cleaner to pass the smog test.also when u bring the car in for the inspection.take it for a rideand get it nice and warmed up.
SOURCE: evaporative emission control system
The evap system allows for gas vapors to be recirculated through the system and burned by the engine,rather than vented into the atmosphere.
It means that the Gas cap is bad,the evap canister is clogged,you have a bad hose,or a sensor is bad.Replace the gas cap first,This is a common problem.

This depends on the problem , like a bad gas cap is not covered but so what a cap is cheap, take it to dealer and let them fix it for free or very cheap. most of the time its a valve, purge valve or vent valve, these are covered, take it before you hit 80,000. good luck.
SOURCE: didn't pass smog due to fuel leak? It passed
Fuel tankes have only one large acess on the top i sugest checkin the rubber gasket for cracks or perishing also check along the fuel lines for damp spots use your nose to locat the strongest area of gas then go from there hope this helps:)

start at the gas cap and trace all lines from one end to the other filling for not seeing (feeling) cracks, a break in the lines, there are multipule lines
