Default Will my fuel check valve trip my evap large leake CEL code??

Ive read posts about a rough long start or having to prime the fuel lines by key bumping 2 or 3 times. id rather fix it. ive had a cel for an evap system large leak and wondered if the check valve on the fuel pump would trip the light? ive checked all the lines and they seem to be good. i havent done a smoke test just yet. thought id get some opinions first. i need it fixed for emissions. i thought you guys would be the best to ask.
