Well I'd start by checking your fuel cap, make sure it's in good shape, then check all the lines in your evap system, at least as many as are easily accessible, to make sure nothing is damaged, unhooked, kinked whatever. All electrical pieces are still hooked up. If everything looks decent, you're probably going to have to take it to a competent repair shop versed in these repairs, below is out of the repair manual, it's complicated: hopefully it's something simple, majority of these tests are beyond the capabilities of home mechanics due to the array of diagnostic tools needed: sometimes it's better to just pay the dealer and get it over with, rather then wasting money and time replacing needless parts hoping.
PRE-DIAGNOSTIC INFORMATION
Note
Enter this Pinpoint Test only when directed here.
The use of a soap solution, such as SNOOP, around the fuel filler cap or the use of the hydrocarbon emission analyzer to determine an evaporative emission system leak is not recommended. The mandatory Rotunda Evaporative Emission System Leak Tester for OBD II (including the ultra-sonic tester) is the only device to be used at this time for evaporative emission system leak detection.
This Pinpoint Test is intended to diagnose the following:
l Canister vent (CV) solenoid (9F945) (electrical concern only)
l Fuel filler cap (9030)
l Fuel tank pressure (FTP) sensor (9C052)
l In-line fuel tank pressure (FTP) sensor (9C052)
l EVAP canister tube (fuel tank to EVAP canister) (9A228)
l Front fuel vapor hose assembly (fuel tank to EVAP canister) (9K313)
l Fuel canister purge outlet tube (EVAP canister to EVAP canister purge valve) (9D661)
l EVAP return tube (EVAP canister purge valve to intake manifold) (9G271)
l EVAP canister purge valve (9C915)
l Vacuum source line (input port vacuum to intake manifold)
l Harness circuits: CV, FLI, FTP, EVAP Canister Purge Valve, SIG RTN, vehicle power (VPWR), reference voltage (VREF) and power ground (PWR GND)
l Powertrain control module (PCM) (12A650)
This Pinpoint Test is used as an assistance in diagnosing the following EVAP components:
l EVAP canister and bracket assembly (9E857)
-- EVAP canister sleeve assembly (fitting) (9D925)
-- Canister vent (CV) solenoid - hose assembly (9F976 or 9K318)
-- EVAP canister (9D653)
-- Canister vent (CV) solenoid - (9F945)(mechanical concern only)
l Fill limit valve assembly (9A086)
l Fuel filler pipe flapper valve (9B085)
l Fuel filler pipe check valve (9189), assembly (9285)
l Fuel tank filler pipe (9034)
l Fuel tank assembly (with fuel vapor vent valve) (9K007)
l Fuel tank assembly (without fuel vapor vent valve) (9002)
l Fuel vapor control valve (9B190) [can be referred to as a grade vent valve (GVV)]
l Fuel vapor vent valve (9B593) [can be referred to as a fill limiting vent valve (FVV)]
l Fuel vapor separator assembly (9B328) [can be referred to as a dust separator]
l Liquid/vapor fuel discriminator (9G332)
l On-board refueling vapor recovery (ORVR) T - connector assembly (9S314)
see what I mean, we can hope it's something simple
