P0452 engine code

[Bolerdweller@hotmail.com]

HI I recently installed a fuel pump in my Jimmy. Shortly after an engine light came on with p0452 code. Not really sure what to look for as the code apparently is a generic evap canister or emissions code and is not specific to the truck? Any one deal with this same issue?

The O-ring for the pump sounds like it isn't seated properly,or there could be pinholes on the top of your tank. It happened to me on my Sonoma. Hopuuefully that helps
