Hey guys, I have a 2001 Silvy that keeps tripping the CEL every time I fill up. It's a problem with the fuel canister purge valve. I have been using my code reader to reset the light, but now the reader wont power on or self test when plugged into the port. I tried the reader in other vehicles and it seems to work fine, so I'm thinking it may be the port itself. I have checked for loose wiring and such. Anyone have any insights on this? Thanks in advance for any help!
